    What is a birth tithi?

    Your birth tithi, also called Janma Tithi, is the lunar day that was running when you were born. It is based on the changing angle between the Sun and Moon.

    There are 30 tithis in a lunar month: 15 in Shukla Paksha, when the Moon is waxing, and 15 in Krishna Paksha, when it is waning.

    A tithi does not start at midnight and may change at any time of day. That is why two people born on the same date can have different birth tithis.

    How this Janma Tithi calculator works

    The calculator uses your birth date, local birth time and birth place to work out the positions of the Sun and Moon at that moment.

    Your result shows the tithi, paksha and lunar month, along with the tithi's start and end times. It also shows nakshatra and vaar for helpful context.

    Because the Hindu lunar calendar and Gregorian calendar follow different cycles, your tithi birthday falls on a different date each year. The calculator gives you upcoming dates automatically.

    How to observe your tithi birthday

    Birth tithi customs differ across families and regions. Many people begin the day with prayer, visit a temple, seek the blessings of parents and elders, or make a donation.

    Some families perform an abhishek, chant the Mahamrityunjaya Mantra, worship their Ishta Devata, or follow a family-specific puja. A simple, sincere observance is enough if that is what suits you.

    If your family follows a particular sampradaya or regional tradition, follow that custom first. Ask a trusted priest for guidance when you need a detailed puja or sankalpa.

    About the sources

    The ritual guidance names the traditional text used for each claim. A chapter or verse is shown only where it has been checked against the text; we do not add a precise reference unless we can verify it.

    Practices and deity lists can differ between texts, regions and sampradayas. We note important differences instead of presenting one custom as universal. Your family tradition takes priority over this general guide.

    Frequently asked questions

    What is my birth tithi?

    Your birth tithi or Janma Tithi is the Hindu lunar day that was active at your exact birth time and place. It is identified by the tithi name, paksha and lunar month.

    Who is my birth tithi deity?

    Each tithi is traditionally associated with a presiding deity. For example, Chaturthi is linked with Ganesha, Saptami with Surya and Ekadashi with Vishnu. Calculate your birth tithi, then open the highlighted tithi to see its deity, pooja, mantra and textual sources.

    Why is my tithi birthday on a different date every year?

    A lunar year is shorter than a Gregorian year. Because the two calendars follow different cycles, the Gregorian date of your tithi birthday changes from year to year.

    Do I need my exact birth time?

    An exact time gives the most reliable result because a tithi can change during the day. If you do not know it, enter your best estimate and treat the answer as approximate.

    Should I celebrate my tithi birthday or date-of-birth birthday?

    You can observe both. Many families use the tithi birthday for prayer or traditional rituals and the Gregorian date for a regular birthday celebration. Follow the custom that feels right for your family.

    What happens if my birth tithi is skipped in a year?

    Sometimes a tithi begins after one sunrise and ends before the next, so it is not present at sunrise on any day. This is called Kshaya Tithi. The calculator marks this case and shows the date to use.

    What if my birth tithi falls on two days?

    A long tithi can be present at two consecutive sunrises. This is called Vriddhi or Adhika Tithi. The calculator marks it and uses the first day for the observance.

    I was born in Adhika Masa. When is my tithi birthday?

    Adhika Masa is an extra lunar month and does not occur every year. In most years, the birth tithi is observed in the matching regular month. The calculator handles this when it finds your anniversary dates.

    What can I do on my birth tithi?

    You can pray, visit a temple, chant a mantra, give food or other useful items in charity, and seek the blessings of your parents and elders. Family and regional customs vary, so follow your own tradition when you have one.
