HOW TO CALCULATE THE POSITIONS OF THE PLANETS As the Ephemeris is calculated for Greenwich at the time when the Observatory clock strikes twelve, it is necessary to make corrections for other hours and for places East or West from that point when it is desired to calculate a horoscope. By adding four minutes for each degree of longitude the birthplace is West of Greenwich to the true local time of birth we obtain the Greenwich Mean Time as recorded by the Observatory clock. This is written G. M. T. We will apply this rule to calculate the G. M. T. of the horoscope for August 2, 8:15 A. M. at Chicago, which is 88 degrees West longitude: H. M. True Local Time of Birth (see page 38)8 23 A. M. Aug. 2 4 min. times 88 degrees equal 352 min. 5 52 Greenwich Mean Time (G. M. T.)... 2 15 P. M. Aug. 2 Multiplying the degree of West longitude of Chicago (88 degrees) by four minutes gives us 352 minutes, which we divide by 60 because there are 60 minutes in each hour. Thus we obtain 5 hours 52 minutes, which we add to the true local time of birth, 23 minutes after 8 in the morning, and the sum is 15 minutes past 2 o'clock in the afternoon, which is the G. M. T. That is to say, at the identical time when the child was born and the Chicago clocks pointed to 15 minutes after 8 o'clock in the morning, the Observatory clock at Greenwich showed 15 minutes past 2 o'clock in the afternoon. This latter is the time we must use to make our calculations of the planets' places, and in order to have as few factors in mind as possible the beginner is advised to forget the local time of birth when once he has found the G. M. T. In Western longitudes the G. M. T. may advance into the day following birth on account of the addition of 4 minutes for each...
