Tithi calculator: the tithi of any date
Enter a date – a birth, the day an elder passed away, a wedding – and see its Telugu calendar date: samvatsara, masa, paksha, tithi and nakshatra. Then see the English dates on which the same tithi of the same masa comes back each year: the birthday by tithi (janma tithi) and the yearly taddinam or abdikam. Any date from 1930 to 2035, computed with the sunrise of the place you choose.
Example: born Saturday 1 January 2000, 6:00 AM, Hyderabad
At that minute it was Pramathi samvatsara, Margashira masam Bahula Dasami, Swati nakshatra. The tithi ran from Dec 31, 9:13 AM to Jan 1, 11:03 AM (sunrise that day 6:45 AM). So the birthday by tithi is Margashira masam Bahula Dasami every year, while the English date moves:

How it works
The Telugu date
A Telugu day runs from sunrise to sunrise, and the tithi given for a date is the one current at sunrise. Months are amanta, new moon to new moon, and each is named after the sankranti that falls in it: the month in which the Sun enters Mesha is Chaitra, the one in which it enters Vrishabha is Vaishakha, and so on. A month with no sankranti is adhika (an extra month) and takes the name of the month after it.
With a time
When you give the time, the tithi current at that minute is used: that is the janma tithi of a birth, or the tithi of a death. Because the Telugu day starts at sunrise, an event at 2 AM belongs to the previous day in the panchangam, but its tithi is still the one current at 2 AM.
The yearly date
The same tithi of the same masa comes once a year, but its English date moves: about 11 days earlier each year, then about 19 days later in a year with an adhika masa.
Birthday by tithi
The day on which the tithi is current at sunrise. If it covers two sunrises, the first day; if it starts and ends between two sunrises (a kshaya tithi), the day it falls in. Jayantis and most vratams follow the same rule.
Taddinam and abdikam
A shraddha is kept on the day the tithi is current in the aparahna: divide the daytime from sunrise to sunset into five equal parts and take the fourth (with a 6 AM sunrise and a 6 PM sunset, 1:12 to 3:36 PM). If the tithi touches the aparahna on both days, the day it covers more of it; if on neither, the sunrise day. Some families follow the kutapa muhurta around noon instead; when the tithi changes near midday, ask your purohit or check a local almanac.
Adhika masa
When the masa comes twice in a year, as an adhika and a nija month, both dates are listed. Families differ on which one they keep.
Which place
A tithi starts at the same instant everywhere, but sunrise and the afternoon depend on the place, so the yearly date can differ by a day between Hyderabad and Chicago. If the birth or death was in one place and the taddinam is kept in another country, give that place under 'Yearly dates for'.
Moon and Sun positions come from precomputed tables of the NASA/JPL DE440s ephemeris with the Lahiri ayanamsa, the same engine as this site's daily panchangam; the arithmetic runs in your browser. We checked the tool against our Python engine on hundreds of dates (tithi, nakshatra, masa, samvatsara and the yearly dates).
FAQ
How do I find my tithi by date of birth?
Enter the date, time and place of birth and press Calculate. You get the tithi, masa and nakshatra of that minute, and below it the dates of your birthday by tithi for the coming years.
How is the death anniversary (taddinam) date calculated?
It is the day on which the masa, paksha and tithi of the death come back, choosing the day on which that tithi is current in the aparahna (afternoon). Give the time of death if you know it: a death after the tithi changed has the next tithi.
Why does my tithi birthday fall on a different date every year?
Twelve lunar months are about 11 days shorter than a solar year, so the date moves earlier each year, and jumps later again when an adhika masa is added.
What tithi applies if someone passed away at night?
The one current at that time. Give the time and the calculator uses it. The panchangam day changes at sunrise, so after midnight the English date changes but the Telugu day is still the previous one.
Which years does it cover?
Any date from 1930 to 2035. Yearly dates are shown up to 2035.
