Tithi anniversaries
Shraddha Tithi · Sahasra Chandra
The day a lunar date falls in coming years — for the shraddha of a loved one, or for the thousandth full moon of a life.
In loving memory
When and where they passed away. From it comes the day each year for their shraddha (ancestral worship) — the day the family seeks their blessings.

Questions people ask
Why does the shraddha date change every year?
Because a shraddha is kept on a tithi (lunar day), not on an English calendar date. Twelve lunar months are about eleven days shorter than a year, so the date moves about eleven days earlier each year, then about three weeks later after a leap month.
Which tithi is used for a shraddha?
The tithi running at the exact moment they passed away, at the place where it happened. Enter the date, time and place, and the page finds it.
Which day is the shraddha kept each year?
The day on which that tithi is running in the afternoon (aparahna) where you perform the rite. The page shows that date, and the offering time, for the city set at the top.
What is the offering time?
Aparahna — the fourth of the five equal parts of daylight, usually early to mid afternoon. It is the traditional hour of the shraddha offering, worked out from your city's sunrise and sunset on that day.
What if we don't know the time they passed away?
Tick “Not sure of the time”. If the tithi did not change that day, you get the answer straight away. If it did, the page shows each part of the day with its tithi and asks you to pick one, rather than guessing.
They passed away in India, but I live abroad now. Which date do I keep?
Keep the date this page shows for the city you live in now. Set your city at the top of the page, and the date and offering time are worked out for you there. Your family in India may keep it a day earlier or later — both are right, because each date is for the place where the rite is done.
I live in India; they passed away abroad. Which date do I keep?
Keep the date this page shows for your town in India. Enter the place they passed away so the tithi is read correctly, and set your own town at the top of the page.
My relatives keep a different date from mine. Who is right?
Both, if each keeps it where they live. The date depends on the place the rite is done. If the family does it together in one place, set that place at the top and everyone gets the same date.
Which time zone is used for the date they passed away?
The time zone of the place you pick from the list. A passing at 9:20 PM in Hyderabad is read on India's clock, even if you enter it from America.
Can I save more than one loved one?
Yes. Save each one with a name and relation, shown in your own tradition's words. They are kept only on your device, encrypted, and never sent anywhere.
