Calculation of Lagna from ephemeris and Table of houses On 01-02-1962 sidereal time at noon is hrs.

Say roughly hrs. 24-35. When it exceeds 24 hours subtract 24 hours. Similarly, when birth is before noon subtract 12 hours. Now we get 00-35 from the Nirayana Table of houses on pp. 72 under col. Madras corresponding to sid. time of 00-35 in col. 1. Lagna is shown as 20° of Mithuna. Again under col. 2 10th house 18° is seen against 00-35. So 10th house cusp is 18° of Meena.

Essentials to be noted in horoscopic epigraphy
I have seen samples of horoscopic writings wherein long list of description of the days are given. But very many of those details are not at all made use of. Sometimes what is most essential (say birth place) is left out. That is not proper. The epigraph should contain all essential elements that are used. Other unnecessary items may be left out. I now narrate 1 to 23 items that are essential. (01) Date of birth In the case of birth from sunrise to midnight, English date and weekday gives correct clue; but in the case of birth from midnight to sunrise confusions may arise if definite indications are not given. For, the date and the weekday of the English calendar are from midnight to midnight while the Hindu or astrological weekday is from sunrise to sunrise. To be more specific it is better to state such night births as between say for example Thursday the 1st February 1962 and Friday the 2nd February 1962 or say so many Ghatis or hours after sunrise on Thursday 01-02-1962. Strictly speaking such a birth say at 01 am should be recorded as 01 am on Thursday the 02-02-1962. (02) Time of birth Better it is stated in Indian Standard Time (IST) which is 5 1/2 hours in advance of Greenwich Mean Noon Time (GMT). If IST is not followed in any place specify the details to correlate with any known measure (GMT preferably). In India from 01-09-1942 to 15-10-1945 the IST was advanced by one hour for war purposes. Recordings of birth during this interval should give details of old & advanced measures. In all cases the safest is to state the interval from sunrise stating the time of sunrise you have reckoned. For in some cases such recordings may not be quite correct. From Lahiri's Ephemeris you can find some more details on observance of timings. (03) Place of birth This is of utmost importance for striking sunrise & Lagna. If you can give the latitude and longitude of the place it would be enough. Otherwise name the nearest important town to gauge them. To find the longitudinal difference in time multiply the degrees of longitude by 4. You get in terms of minutes. That gives the difference in time from 05-30 (IST). For example Bangalore is 77° 34'. This multiplied by 4 gives 310 minutes or 5 hours 10 minutes. The standard time in India corresponding to GMT noon being 05-30 pm, the corresponding LMT at Bangalore is got by deducting 20 min. Similarly in cases of longitudes higher than 82 1/2 degrees yielding times greater than 05-30, you must add the difference to get the local time. (04) Sunrise Note the sunrise of the place on the day of birth in IST. If you cannot get it for the birth place you can evaluate by adding or subtracting (as the case may be) the longitudinal difference in time between the birth place and a known place of which sunrise may strike correctly. As sunrise and sunset are more or less the same on the same date of an English month in all years you may refer to any year details for this purpose. (05) Weekday For astrological purposes always reckon weekdays from sunrise to sunrise. For the evaluation of weekdays read my commentary on naming of weekdays by the theory of Hora.

This is the chief key for success in predictions. For as may be seen later even a minute's difference in Lagna capsizes the entire reading. So you must fix it up not by strict mathematical calculations by direct method but by a reverse process of verification of some of the important past events with the aid of division charts. Please read my Chapter on division charts (vide part II of NTP). page ~ 32 ~
