LESSON XVI

INTRODUCTION

   Lesson XVI concerns the concept of time and why it is so important to you as an astrologer. This lesson is short in length because it is very important and complex and you must read it over a few times till you understand it. You need not memorize it but you must understand it. The element of time is what produces the individuality of every horoscope. It will be necessary for you to know the exact time - hour, minute, - when your client was born. This time will be solar time (time which is based on the movement of the Sun). You must learn our method to convert this into Sidereal time, (pronounced SY DEAR-EE-AL) which is true star time based on the motion of the universe. Our method for the computation of star time (Sidereal time) is not difficulty however, if you do not give it your undivided attention, you may become confused.

   It is our contention, that the simpler these computations are, the better for the student. For example, there are many people in the world who have acutely logical minds, and possess amazing inherent powers for character a analysis. Such people are well-adapted for astrological interpretation. However, they may have an ardent dislike for figures, and shy away from anything which involves complicated calculations. What a shame that many people of this type are prevented from astrological investigation for such a senseless reason! It seems to us that many astrologers have purposely complicated the computations to build up their own egos. We will present this concept of time and computation in an easily comprehensible manner, so that even those with a deep-down phobia for figures are able to proceed in their astrological development. It is imperative that you realize that our method is efficient and complete, and that it produces the exact precision of more complicated systems.

   No horoscope can be accurately erected until you have mastered several basic factors concerning time. Dating from the early history of Society, the various governments of the world have tried to simplify man's relationship to time. In so doing, and in continually changing these simplifications, they have created endless difficulties for the astrologer, who is trying to calculate the true Sidereal time for a given event or birth. In this Lesson, the reasons for the calculations to be made are explained, and definitions are given for all terms used. (As the same understanding is required of a student of astronomy, surveying, aerial or marine navigation, fuller explanations of the principles involved will be found in textbooks dealing specifically with these subjects.) As much of this is of interest to the general public, the same explanations can be conveniently found in a necessarily restricted section of Whitaker's Almanac. Every practicing astrologer should always keep a copy of the current edition of some Almanac, as it is extremely useful for reference.

LOCAL MEAN TIME

   Before we can calculate a horoscope, we need to understand the various kinds of time. LOCAL MEAN TIME gives us exactly noon when the Sun is directly overhead, or rather, at its highest place in the heavens. Since the Sun apparently moves in relationship to the Earth, it stands to reason that the actual time of noon will vary as we happen to live in various places, for example, when it is 7:00 A.M. in Philadelphia, it is noon in London.

   The Sun moves approximately sixty miles every four minutes. This average sixty miles forms one degree of longitude, hence the Sun travels one degree of longitude in four minutes of time, or 15 degrees to the hour. Suppose a certain city is sixty miles or so west of your birthplace, the Sun will not reach this other city for four minutes. In the past, each city or country place maintained its own time, but as people moved more frequently, they argued about the correctness of their watches so much, that Standard time was introduced. Before we can set up the angles of the horoscope, we first need true Local Mean Time. Therefore, when the birth time is given, it is given in Standard time, and it is necessary for us to convert it to Local Mean Time. This procedure is very simple and should cause you no trouble. Remember that this correction is simply to find the true local mean time. More computation is necessary before we can erect the chart but this is our beginning.

STANDARD TIME

   On November 18, 1883, Standard Time was inaugurated in the U.S. (and Canada). However, the geographical lines of the Time Zones were not definitely established until March 19, 1918. For example, the state of Georgia did not change to Eastern Standard Time until then. Previously, it had been on Central Standard Time.

   Since the meeting of train schedules, etc., is impossible on the basis of local time, Standard Time Zone meridians were spaced at intervals of 15 degrees of longitude east and west of Greenwich, and all clocks within each zone were adjusted to the mean Solar time of the mid-point of the zone. The material which follows need not be memorized. You will refer to it many times in the future and eventually it will become part of you.

Time Belts of the U.S.

  1. Eastern Standard Time - E.S.T. is calculated to the 75th meridian west longitude.
  2. Central Standard Time - C.S.T. is calculated to the 90th meridian west.
  3. Mountain Standard Time - M.S.T. is calculated to the 105th meridian west.
  4. Pacific Standard Time - P.S.T. is calculated to the 120th meridian west.
  5. Alaska was standardized in 1918 on 150th Meridian west, but in actual practice, other zones are and have been in use: 120° 150°, 165°.*

*If you look in an Ephemeris or an Atlas, and you find that the place where you were born is exactly on the 75th, 90th, 105th, or 120th meridians, you need make no calculations for Local Mean Time. It will coincide with Standard Time. Again, if you were born previous to November 18, 1883, no correction is needed. In the following exercises, the meridians are correct only to the nearest degree.

Some Simple Exercises in Converting Standard Time to Local Mean Time

Ex. 1. If you were born in New York City at 4:10 A.M. Eastern Standard Time (E.S.T.), what is your Local Mean Time?

   Any map will indicate to us that New York City is 74 degrees WEST of Greenwich, that is to say, that it is 1 degree east of the 75th meridian. Therefore the Sun has already passed over N.Y.C. before it reaches Philadelphia, or rather, the 75th meridian. It will have taken four minutes to travel this distance, hence when the Eastern Standard clock at either Philadelphia or New York shows 4:10 A.M., it will be 4:14 A.M. Local Mean Time in New York City.

Ex. 2. Suppose you were born in Dallas, Texas, at noon (12:00 P.M) C.S.T., what is your L.M.T.?

   A map or ephemeris tells us that Dallas is 96'/2degrees west of Greenwich, that is, 6'/2degrees west of the 90th meridian. 6'/2 degrees equals 26 minutes (Note: when the place in question is west of the meridian, we subtract the time correction; when it is east of the meridian, we add it.), thus the L.M.T. for Dallas, Texas at noon is 11:34 A.M.

Ex. 3. Suppose you were born in Los Angeles, California at noon P.S.T., what is your L.M.T.?

   The ephemeris or map shows us that Los Angeles is 118 degrees west, or 2 degrees east of the 120th meridian. 2 degrees yields 8 minutes. The Local Mean Time in question will be 12:08 P.M.

Ex. 4. If you were born in Minneapolis on June 2, C.S.T. midnight (12:00 A.M.), what is your Local Mean Time.

   Minneapolis is 93 degrees west, that is, 3 degrees west of the 90th meridian. 3 degrees yields 12 minutes (for west, remember we subtract). Therefore, the L.M.T. is 12 minutes before midnight on June 2, so in actuality you were born at 11:48 P.M. on June 1.

Ex. 5. Suppose you were born in Washington, D.C. at 7:15 P.M., E.S.T., what is your L.M.T.?

   Washington, D.C. is 77 degrees west, or 2 degrees west of the 75th meridian. 2 degrees yields 8 minutes of time. For places west of the meridian that sets the time, subtract these minutes, hence your L.M.T. is 7:07 P.M.

   With this method, discovering the L.M.T. for anyone born in the U.S. is a simple matter. You need only be able to add and subtract, and these computations will never involve difficult numbers.

Foreign Standard Time

   Europe is divided into three belts of time.

I. Greenwich Mean Time (G.M.T.) is set for zero longitude. At an International Meridian Conference in 1884, it was agreed by astrologers of the leading nations that they would use the meridian of Greenwich as the zero degree on all maps. Greenwich Mean Time is used throughout Great Britain, France, Belgium, Holland, Luxemburg, Spain, Portugal, Algeria, and Morocco.

2. Middle or Central European Time (M.E.T. or C.E.T.) is standardized on 15 degrees east longitude. It is used in Germany, Sweden, Norway, Austria, Hungary, Poland, Switzerland, Italy, Czechoslovakia, and Yugoslavia. The time is one hour fast of Greenwich, hence subtract one hour to obtain G.M.T.

3. Eastern European Time (E.E.T.) is standardized on 39 degrees east longitude. It is used in Turkey, Greece, Bulgaria, Romania, Estonia, Latvia, Finland, Egypt, Palestine, and the Union of South Africa. The time is two hours fast of Greenwich, hence you subtract two hours to obtain G.M.T.

   You will find the following notes on time in foreign countries useful, particularly if you ever become interested in Mundane Astrology.

   India went on Standard Time on January 1, 1906. It is standardized on 82'/2degrees east longitude, i.e., 5'/2 hours fast on G.M.T. Note that Calcutta is not on this standard. It is 5 hours 53 minutes 21 seconds fast of Greenwich.

   Burma is standardized on 97'/2grees east longitude, i.e., 6'/2 hours fast of G.M.T.

   Indo China and Thailand are standardized on 105 degrees east longitude, i.e., 7 hours fast of G.M.T.

   Western Australia, Hong Kong, and the Philippines are standardized on 105 degrees east longitude, i.e., 8 hours fast of G.M.T.

   Japan and Korea are standardized on 135 degrees east longitude, i.e., 9 hours fast of G.M.T.

   Eastern Australia is standardized on 150 degrees east longitude, i.e., 10 hours fast of G.M.T.

   Marshall and Soloman Islands are standardized on 165 degrees east longitude, i.e., 11 hours fast of G.M.T.

   New Zealand, Guam, and Samoa are standardized on 172'/2 degrees east longitude, i.e., 11'/2 hours fast of G.M.T.

PLACES IN THE WESTERN HEMISPHERE

   Argentina and some of the West Indian Islands use Atlantic Time, which is standardized on 60 degrees west longitude, i.e., four hours slow of G.M.T.

   Newfoundland, Labrador, and Uruguay are standardized on 52'/2 degrees west longitude, i.e., 3'/2 hours slow of G.M.T.

   Canada uses Atlantic Time for places east of 60 degrees west longitude, such as Nova Scotia. From 60 degrees west to 90 degrees west, Canada is standardized on the 75th meridian, i.e., four hours slow of G.M.T.

   Puerto Rico, Chile, and Paraguay use Atlantic Time, four hours slow of G.M.T.

   The Panama Canal Zone uses Eastern Standard Time, five hours slow of G.M.T.

   Hawaii is standardized on 157'/2 degrees west longitude, i.e., 10'/2degrees hours slow of G.M.T.

   The U.S.S.R. is divided into ten zones of time, extending from 30 degrees east longitude to 150 degrees east. These zones occur regularly at intervals of 15 degrees, each equivalent to one hour of time.

Some exercises to obtain Foreign Local Mean Time

Ex. 1. If you were born in Paris at noon by the clock, what is your L.M.T.?

   Paris is 2 degrees 0 minutes east of the Greenwich Meridian which is 0°, hence you will add 8 minutes. Your L.M.T. is 12:08 P.M.

Ex. 2. If you were born in Berlin at noon by the clock, what is L.M.T.?

   Berlin is 13 degrees 24 minutes east of the Greenwich Meridian. The difference to the 15th meridian is 1° 36', hence for west of this meridian, you subtract six minutes. Your L.M.T. is 11:54 A.M.

Ex. 3. If you were born in Jerusalem at noon by the clock, what is your L.M.T.?

   Jerusalem is 35° 14' east. This is 5° 15' east of the 30th meridian, so add 21 minutes. Your L.M.T. is 12:21 P.M.

Ex.4. The Korean War started at 4:00 A.M. on June 25, 1950 by Korean Standard Time. What was the L.M.T.?

   Seoul is 127°, which is 8° west of the 135th meridian that sets the time, hence subtract 32 minutes to get the L.M.T., which will be 3:28 A.M.

Ex. 5. At the request of Burmese astrologers, Burma declared itself a republic on January 4, 1948, at 4:20 A.M., in Rangoon. What was the L.M.T.?

   Rangoon is 96 degrees east and the meridian that sets the time is 97'/2 degrees east. Thus Rangoon is l'/2 degrees west of the meridian. Subtract 6 minutes and the L.M.T. will be 4:14 A.M.

Daylight Savings Time

   This is sometimes referred to as Summer Time. It is the pet aggravation of astrologers. This was originated in England in 1916. It consists of the arbitrary setting ahead of the clock by one hour, thereby shifting all the day's activities an hour earlier, ending the work day that much sooner and leaving an hour more of daylight in which to indulge in seasonal recreations. In general, it commences at 2 A.M. of the Sunday following the third Saturday in April, and ends on the Sunday following the third Saturday in October. For births occuring during this time, the astrologer must subtract one hour to obtain the correct Standard time.

   WAR TIME was invented during World War II. This means that the clock was set one hour ahead during both the summer and winter. In the U.S., War Time began February 9, 1942, and ended September 30, 1945. All you must do for people who were born during this time is subtract one hour, from the birth time to obtain true Standard Time. Remember this calculation must be made regardless of whether it was winter or summer as War Time embraced the entire year.

   DOUBLE SUMMER TIME - During World War II, some European countries used War Time all the year around, but during the summer they employed what they called Double Summer Time. This simply means that the clocks were turned ahead by two hours. You must subtract two hours when computing the horoscope of a person born during this time. Any almanac will list which countries employed Double Summer Time.

   GREENWICH MEAN TIME - The position of the planets in some ephemerides is given in Greenwich Mean Time, which is simply the Local Mean Time of the suburb of Greenwich, four miles South East of London. Through this suburb the zero degree of longitude passes. The Royal Observatory is located there. In London, time is sometimes stated in Greenwich Civil Time, meaning that no correction has been made from Greenwich for the four mile distance. However this does not concern you. This Civil Time is stated simply for reference.

   SIDEREAL TIME (S.T.) - Sidereal Time is time measured by the stars, and not by the Sun. Sidereal Time is slightly faster than Sun Time. If a fixed star if exactly overhead on any particular day, and the Sun if also overhead then on the following day, that is, 24 hours later, the Sun will arrive at the same overhead portion approximately four minutes later than the fixed star. The star or sidereal time is therefore much more accurate and that is why we use it. There are many more complicated aspects of sidereal time but this is all you are required to know at this point.

Sample Chart Erection

   In order for you to accurately erect a horoscope, you need an Ephemeris, a Table of Houses, and a lot of concentration and patience. The Ephemeris which we use and strongly recommend is The 200 Year Ephemeris, by Hugh MacCraig. We feel that it is the most useful and inexpensive for our students and graduates. The Table of Houses we employ is the A-P Table of Houses. It not only includes computations for the Equator to 66 degrees North Latitude, but also a simple method for using the same tables for Southern Latitudes.

   With these two books and the simple application of our chart erection principles, you can compute the figures for any horoscope. All you need now is a sheet of blank horoscope charts. In this lesson we show you reprinted pages of these books to demonstrate their use. You may use any ephemeris and table of houses. The following is a sample of the computations for the erection of a natal horoscope. (Just to refresh your memory, we refer to a natal horoscope as a nativity).

   In the erection of this chart we follow the method employed by Hugh MacCraig in the above-mentioned 200 Year Ephemeris. The Table of Houses which we use for this example is the A-P Table of Houses. With these two books, we are equipped with all the necessary data for calculating any astrological chart.

   In all astrological work, it is at all times advisable to adopt a regular method of procedure, which will save you time and make your work more efficient and satisfactory. The following principles of procedure have been adopted by us, and we recommend them to you.

   Principle I. Write down all the birth time information.

   Ex: The birth information for our hypothetical chart is June 6, 1949, 11:20 AM. in Bronx County, New York City.

   Principle II. Using MacCraig's Ephemeris, we find and make note of 1) the Longitude of the Bronx, 2) the Latitude, 3) the Longitude calculated in time. (Note: The Bronx is part of New York City, hence there is no separate listing for it Therefore, the longitude and latitude of New York City will suffice.)

   Ex.: 1) Longitude: 73W57 2) Latitude: 40N45 3) Longitude in Time: 4:56. This is necessary for a slight time correction which will be explained in a future principle.

The Concepts of Longitude and Latitude

   On almost every map you will find lines drawn North and South. These are the longitude lines or meridians. The lines from East to West are called Latitude lines. Any city or town is located by:

  1. The number of degrees east or west of London or rather, east or west of the Greenwich Observatory, which is the starting place of the zero degree of longitude. SEE DIAGRAM I, LONGITUDE LINES
  2. The number of degrees North or South of the Equator, which is the zero degree of Latitude. SEE DIAGRAM II, LATITUDE LINES

   It is obvious why longitude and latitude are so important when we are studying the concept of time in relationship to a given point on the Earth.

   Principle III. We must determine:

  1. Which Standard Time Zone the time is given in.
  2. If Daylight Savings Time was in effect at this time.

   Ex. 1) E.S.T. 11:20 A.M.-N.Y. is part of the Eastern Standard Time Zone.

   Ex. 2) From the date June 6, we know that Daylight Savings Time was in effect. To correct this, we merely subtract one hour from the existing time.

- 1:00

 

 

 

 

 

 

 

 

10:20

 A.M.

 

 

 

 

 

 

   Principle IV. The result from Principle III is True Standard Time. This must be converted into Local Mean Time. To do this we (1) find the number of degrees of Longitude the location (Bronx New York City) is East or West of the Time Meridian which sets the standard of the part of the world for which the chart is being erected. (2) Multiply this number of degrees by four. (3) a. If the location is East of this meridian which sets the Standard Time, add the number of minutes, b. If the location is West of this meridian which sets the Standard Time, subtract the number of minutes.

   In other words, add four minutes for each degree of longitude the location is East of the Standard Time Meridian, or subtract four minutes for each degree it is West. The result will be the L.M.T. Always remember that the Earth is turning from West to East, and therefore time will be earlier in locations East of the Time Meridian than in locations West.

Ex.: The Standard Time Meridian in question (for Bronx, New York) is the 75th Meridian. The Meridian for the chart example is the 73rd. This is 2 degrees East of the Standard 75th Meridian. 2 degrees multiplied by 4 minutes yields eight minutes of time. Because it is East, we add.

 

11:20

+ 00:08

 

 

 

 

 

 

 

 

10:28

A.M. L.M.T.

 

 

 

 

   Principle V. Calculate the interval of time between the noon previous to the birth or event, and the actual L.M.T.

   Ex.: 10:28 A.M.

   From the noon previous to the birth this is 22 h, 28' 00". (NOTE: ' sign means minutes " sign means seconds)

   Principle VI. This interval of time must be corrected at the rate of approximately ten seconds per hour. This correction is necessary for precision as the time found in Principle V is solar time and must be adjusted to make it equal Sidereal Time. This correction is always added to the interval of time as found by Principle V. Ex.: On page 17 in MacCraig's Ephemeris, there is a simple table which simplifies this process. It indicates that our correction amounts to the following (This table is reprinted here for your convenience): SEE DIAGRAM III.

 

22h corrects to

 

3' 37''

 

28' corrects to

 

+ 5''

 

 

 

3' 42''

which must be added to our figure attained by Principle V. Thus we have:

 

22h 28' 00''

 

 

 

 

 

 

 

 

+ 00h 03' 42''

 

 

 

 

 

 

 

 

22h 31' 42''

or 22 hours 31 minutes 42 seconds

 

 

   Principle VII. Remember in Principle II we made note of the Longitude in Time. We now must make use of the correction for this time. The Longitude in time must be corrected in the same manner as the time in Principle V by allowing approximately ten seconds for each hour, to adjust the location to the Sidereal Time. If the location of the birth or event is West of Greenwich, add this correction to the interval of time as found by Principle V and corrected by Principle VI. If the location is East of Greenwich, we must subtract it.

   Ex. Once again referring to MacCraig's Chart on page 17 of the Ephemeries, we find that 4:56 corrects to 00h 00' 48'', SEE DIAGRAM III. Thus:

 

22h 31' 42''

  (Note: 90'' = 1' 30'')

 

 

 

 

 

+ 00h 00' 48''

 

 

 

 

 

 

 

 

22h 32' 30''

 

 

 

   Principle VIII. We must now compute the Sidereal Time for the noon previous to the birth or event. On Page 7 of MacCraig's Ephemeris, there is a Master Table of Sidereal Time which provides us the necessary information to do this. This table is reprinted here for your convenience. SEE DIAGRAM IV.

   Ex.: Following the directions from MacCraig, we now have as the Sidereal Time previous to the birth or event:

 

   4h 47' 35''

 

 

 

 

 

 

 

   Principle IX. To the Sidereal Time for Noon achieved by Principle VIII, add the time resulting in Principle VII. The result is the Sidereal Time of the Chart for the birth or event. If the Time thus obtained exceeds 24 hours, then we must subtract 24, and use the remainder. Ex.:

 

22h 32' 30''

 

 

 

 

 

 

 

 

+ 4h 47' 35''

 

 

 

 

 

 

 

 

27h 20' 05''

 

 

 

 

 

 

 

 

- 24h 00' 00''

 

 

 

 

 

 

 

 

3h 20' 05''

 

 

 

 

 

 

 

   Principle X. We now turn to the Table of Houses, and under the proper Latitude, we select the Sidereal Time which is nearest to the Sidereal Time for the chart, and from the Tables, find the Signs and degrees and place them on the proper House cusps of the chart.

   Ex.: The nearest latitude listed in the A-P Table of Houses is 40° 43'. The nearest Sidereal Time listed under this latitude is 3h 22' 23". The Table for this time reads as follows:

   X house

23o

   XI house

28o

   XII house

1o

   ASC house

28o  52'

   II house

22o

   III house

20o

   The Signs are thus inserted in your chart and the result is this: SEE DIAGRAM V.

   As you can see, only six Signs are listed in the Table of Houses. Please study the diagram and observe that for each Sign given, the opposite Sign goes on the opposite cusp, and the degree of the Sign given corresponds to the degree for the opposite Sign.

   Please also make note of the interception of Cancer in the Eleventh House and Capricorn in the Fifth House. (The whole concept of interception will be studied in a future lesson dealing with delineation.)

   There are two additional steps which Hugh MacCraig employs to obtain a more precise Medium Coeli and Ascendant. We do not feel that these additional steps are necessary, and therefore are omitting them from our study. They are amply explained in MacCraig's book if you wish to consider them, but your accuracy is unchallenged without them.

CONCLUSION: LESSON XVI

   Although this Lesson may appear short to you, its importance cannot be over-emphasized. At this stage of our study, quality and not quantity is of paramount significance. In this past Lesson, you have studied our method for determining the positions of the Signs in relationship to the Earth. You now also realize the intricacies of the different types of time and their relationship to our work. Remember that you should comprehend completely the facts which have been presented to you before you take your exam. In the next Lesson, we shall study the computations involved for ascertaining the exact positions of the planets for any time needed.
