The day of the calendar has its reference point at 0:00 midnight (local time or according to time zone).
The astrological day extends from sunrise of the current day to sunrise of the next day. Sunrise of birth is the
sunrise before birth, i.e. a birth after midnight and before sunrise belongs to the previous day
of the normal calendar.
Varsha, Masa, Dina and Hora are only defined for the the astrological day.
Hora: The Astrological Hour
The time from sunrise to sunset is divided into 12 equal parts (the day) and 12 parts from sunset to next
sunrise (the night). The first Hora lord of the day is the day's lord. The other lords will follow in their order:
Saturn - Jupiter - Mars - Sun - Venus - Mercury - Moon - etc.
Example
The sublords for sunday are
For the day: Sun - Venus - Mercury - Moon - Saturn - Jupiter - Mars
- Sun - Venus - Mercury - Moon - Saturn (12)
For the night: Jupiter - Mars - Sun - Venus - Mercury - Moon - Saturn - Jupiter - Mars
- Sun - Venus - Mercury (12)
Other Methods of Hora Calculation
There are at least 2 other views about Hora calculation (currently not supported
by Maitreya)
The time from sunrise to next sunrise may be divided into 24 equal parts.
This rule gives other results than the method explained above.
The start of the day may be placed at 6:00 local time. So each Hora gets
exactly 1 hour of time.
Varsha (Year)
Rule
Varsha lord can be calulated if we have the year of the date. The rule is
varshaLord = (( year + 3 ) * 3 ) mod 7
where the planets are in their natural order (Sun .. Saturn), i.e. zero is the Sun, 1 is Moon etc.
Example: The year 2004 yields
(2004+3) * 3 = 6021, divided by 7 yields 1. So Moon is the lord of the year.
The table below gives examples for Varsha lords of several years.

Masa: The Month
Rule
Masa lord can be calulated if we have the year and month of the date. The rule is
masaLord = (( 12 * year + month + 6 ) * 2 ) mod 7
where January is 1 and the planets are again in their natural order (Sun .. Saturn).
Example: November 2006 yields
(12*2006 + 11 +6) * 2 = 48178, divided by 7 yields 4. So Jupiter is the lord of the month.
