NECESSITY OF CONVERSION OF RECORDED TIME OF BIRTH INTO LOCAL MEAN TIME:
All the births are recorded in Standard time. Standard time is a uniform clock time
used throughout the country, based upon the local mean time of a certain geographical
meridian passing through the country and arbitrarily chosen by law, for the sake of
convenience and facility. All watches and clocks are accordingly set to show the time.
Countries with large land area and several meridians passing through that country
will have different local mean time depending on the longitude of the place. Therefore,
the time of birth recorded from the clock is not the actual time of birth.
Local mean time at any given meridian is the true mean time at all places which lie on
that meridian, irrespective of the latitude. Therefore, it is necessary to convert the
Standard time (clock time) into local mean time. To convert the Standard time into local
mean time add (or) subtract 4 minutes to every degree of longitude according to the
place is in East or West of Standard Meridian. In India the Standard meridian is 82 deg
30 min East of Greenwich.
CASTING OF HOROSCOPE
Details required for casting the horoscope:
1. Date of birth
2. Time of birth
3. Place of birth
I step: Convert the recorded time of birth into local mean time.
II step: Find out the date of birth in the Almanac in a particular year and note
down all the details given for that day in the Almanac. In most of the
Almanacs position of the planets are given in Nakshtra Padas and by
copying them, Rasi and Navamsa chart can easily be drawn.
TO FIND OUT JANMA LAGNA OR ASCENDANT:
III step: In some almanac’s (Panchanga’s) every month, for every date the
beginning or ending times of lagnas will be given in a table form. By
observing those tables the lagna can be fixed for the time of birth of the
child.
In some Panchanga’s the date-wise tables are not given for different lagnas. But
either the balance portion of rising sign on every day of a month at sunrise will be given
or the elapsed portion of rising sign at sunrise will be given. If the elapsed portion of
rising sign at sunrise is given, from this balance portion of that lagna is to be found out
by deducting the elapsed portion from the total duration of rising sign, then by adding the
duration of subsequent lagnas, the lagna at the time of birth can be found out . From that
we can find out the elapsed portion and balance portion of the lagna at the time of birth.
This is explained in the next paragraph.
Note down the time of sunrise on the day of birth. Deduct sun rise time from birth
time. So you will get the elapsed time from sunrise in hours. Convert the hours into
Ghatikas (or) Nazhikas.
24 hours – 60 Ghatikas
24 minutes – 1 Ghatika
24 seconds – 1 Vighati
Example:
For instance the native was born at Chennai at 11-31 AM on 14th day of April 1997
corresponding to the cycle year Prabhava in Solar Month Mesha (Chaithirai) 1st Tuesday.
The Sun rise at Chennai on 14.4.1997 6-01 AM
The birth time of the native 11-31 AM
Deducting the sun rise time from the birth time we get 5 hours and 30 minutes.
5 hours is equal to 12 Ghatikas 30 Vighatikas
30 minutes is equal to 1 Ghatikas 15 Vighatikas
Total 13 Ghatikas 45 Vighatikas
Therefore, the birth has taken place at 13 Ghatikas 45 Vighatikas. (This is
called Udhayadhi Nazhikas.
TO FIND OUT THE BALANCE OF RISING SIGN ON THE DAY OF BIRTH AT SUNRISE:
(i) If the Almanac is referred, you can find out the Ghatikas remaining to be covered
(Balance portion of rising sign at sunrise) by the sun in the solar month when the
child was born against solar date of birth.
(ii) Without referring to the Almanac, we ourselves can work out the balance portion
of rising sign at sunrise. On the first day of Mesha (Solar month Chittirai) the first
deg of Mesha rises in the Eastern horizon at sun rise and the remaining signs
gradually ascend till the next day at sun rise, On the second day of mesha the
sun rise will take place in the second degree of Mesha. The Sunrise takes place
in the last degree of Zodiac on 30th day of Meena, when the solar year ends. Thus
the Lagna (or) Ascendant is the particular point of ecliptic considered with
reference to particular horizon. Certain period of time is allotted to each of the
Zodiacal Signs to rise, the duration of such periods will vary depending upon the
latitude of the place. This is called Rasimana.
The degree and the sign in which; the sun rises at the time of birth will be
ascendant at that particular time. From the Almanac find out in which solar month the
child is born. Note down the total duration of rising Sign (Rasimana) for the given solar
date of that month for the given latitude of the birth place, calculate the balance of rising
sign at sunrise on the day of birth and note down the total duration of subsequent signs
also. Rasimana is given in Ghatikas and Vighakitas. Divide the total duration of rising
sign (Rasimana) by the total number of days of solar month. You will get the movement
of sun in one day. Multiply it by number of solar days crossed by sun (i.e. upto previous
day of birth) till sun rise on the day of birth. Add the duration of next Signs rising with the
Balance of rising sign on the day of birth (solar day) till you get the time of birth in
Ghatikas. Find out in which sign the Lagna falls. Note down duration of Lagna sign.
Divide 30 deg by total duration of the Lagna sign and Multiply it by the time of birth in
Ghatikas after sun rise. You will get the degrees and minutes passed by Lagna. We
know that each sign is composed of 30 deg and 9 Quarters of constellation. So one
quarter of sign will measure 30/9=3 1/3 deg (3deg 20 minutes). By which we can easily
find out in which Nakshatra pada the Lagna falls.
POSITION OF THE MOON
Examine the Almanac and find out the constellation (or) ruling star at the time and
day of birth. Find out the total duration of the star. Divide it by 4, you will get duration of
one Nakshatra pada. Calculate the balance portion of the Nakshatra at the time, and day
of birth by deducting the elapsed portion of Nakshatra from total duration of the
Nakshatra. Find out in which Nakshatra pada, the ruling star falls by working out number
of Nakshatra pada elapsed at the time of birth.
DASA BHUKTI
Divide the total Dasa period by total duration of the ruling star and multiple it by
balance portion of ruling star. You will get the balance of Dasa period in years, months,
and days.
NAVAMSHA
Work out the total number of Nakshatra padas from Aswini 1st pada to the star
pada in which the planet is posited. Divide the total no. of padas by 12. Count the
reminder from Mesha you will get the Navamsa sign in which that planet is posited.
