Calculcation

There are two different meanings of the word day
1. The day of the calendar has its reference point at 0:00 midnight (local time or according to time zone).
2. 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.

Lord Examples Years
Sun 1999, 2006
Mercury 2000, 2007
Saturn 2001, 2008
Mars 2002, 2009
Venus 2003, 2010
Moon 2004, 2011
Jupiter 2005, 2012

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.

The table bellow gives examples for Year lords of several years.

Lord Examples Months
Moon Jan 2007
Mercury Feb 2007
Venus Mar 2007
Sun Apr 2007
Mars May 2007
Jupiter Jun 2007
Saturn Jul 2007

Dina: The Day

Dina lord is the weekday lord of the ordinary calendar, i.e. Sunday's lord is the Sun, Monday's lord is the Moon etc.
