📖 What is Thivasam (Death Tithi)?

In Hindu tradition, the annual death anniversary of a family member is called Thivasam (also Thevasam or Shraddha). Unlike a Gregorian anniversary, it is not observed on the same calendar date each year. Instead, it is observed on the same Tithi — the lunar day of the Hindu calendar — that corresponds to the day of passing.

Because the lunar calendar shifts relative to the solar calendar, the Gregorian date of the Thivasam changes every year. This calculator identifies the Tithi at the time of passing and then finds the dates in upcoming years when that same Tithi recurs.
