The shraddha guide

Which day is the shraddha?

The day moves every year, and the question comes up a fortnight too late. Here are the sixteen days, the rules behind them, and how to find the day from a date of death.

Pitru Paksha, the sixteen shraddha days

The fortnight runs from the full moon of Bhadrapada to the next new moon. Each day has its tithi, and a household keeps the day whose tithi matches the one their person died on, not the calendar anniversary.

About the dates

The ladder below is a rule, so it holds in every year. The calendar dates it falls on are not listed here yet. Until they are, take them from your family's panchang.

Computed, checked
DayTithiHow it is kept
01PurnimaProstapadi, Rishi TarpanThe full moon on which the fortnight opens. Many households treat it as the eve rather than as a shraddha day of its own, and begin counting from the next morning.
02PratipadaKept by the households whose person died on this tithi.
03DwitiyaKept by the households whose person died on this tithi.
04TritiyaKept by the households whose person died on this tithi.
05ChaturthiKept by the households whose person died on this tithi.
06PanchamiBharani Panchami, Kunwara PanchamiIn several regions this day is kept for those who died unmarried. Where the Bharani nakshatra falls elsewhere in the fortnight, the Bharani shraddha moves with it rather than with the tithi.
07ShashthiKept by the households whose person died on this tithi.
08SaptamiKept by the households whose person died on this tithi.
09AshtamiKept by the households whose person died on this tithi.
10NavamiMatru Navami, Avidhava NavamiKept for the mothers of the line, and in many households specifically for a married woman who died before her husband.
11DashamiKept by the households whose person died on this tithi.
12EkadashiKept by the households whose person died on this tithi.
13DwadashiSannyasi ShraddhaKept for those who had taken sannyasa. Some traditions place this on Ekadashi instead, and a few keep both.
14TrayodashiKept by the households whose person died on this tithi.
15ChaturdashiGhayala ChaturdashiKept for those who died by accident, by weapon or by violence. Many traditions hold that an ordinary death belongs elsewhere in the fortnight, so a family is sometimes told that its remembered tithi does not apply here.
16AmavasyaSarva Pitru Amavasya, Mahalaya AmavasyaThe day the fortnight closes, kept for all the departed of a line together, and for anyone whose tithi went unrecorded.

The named days

The names above are regional conventions and differ between communities, sometimes between two families on one street. They are printed so you recognise a name when someone uses it. Your own family's purohit has the final word.

If the tithi is not known

Sarva Pitru Amavasya, the last of the sixteen, is kept for all the departed of a line together and for anyone whose tithi went unrecorded. For families two or three generations out of India this is often the day, and the tradition provides it for this case.

Where the timings come from

Every date here is computed: the tithi at the ghat's sunrise, the month named by the sankranti it holds, and the sun's entry into each sign under the Lahiri ayanamsa. Tithi, nakshatra, sunrise and windows were checked against Drik Panchang for Haridwar on eight days between September 2026 and March 2027, to the minute. The dates roll forward each morning.

The muhurat calendar's dates come from these rules and roll forward each morning.

Why the date moves

A tithi is one thirtieth of a lunar month, the time the moon takes to gain twelve degrees on the sun. It lasts anywhere from about nineteen to about twenty-six hours. Twelve lunar months come to about 354 days, against 365 in the calendar year.

  • The eleven-day slip

    The lunar year is about eleven days short. A tithi that fell in late September this year falls in mid September next year, and over three years the drift is a month. That is why a father's shraddha and the date on his death certificate are two different things.

  • The inserted month

    About every thirty-two and a half months an extra lunar month, the adhika masa, is added to bring the calendar back in line with the sun. In that year the occasion moves about nineteen days later instead of eleven days earlier. A family that subtracts eleven days by habit is wrong in the one year it matters.

  • A tithi has its own start and end

    A tithi begins and ends at the hour the moon reaches its mark, and the Hindu day turns at sunrise. So a tithi can begin on Tuesday afternoon and end on Wednesday evening. Which of the two days carries the observance is settled by a rule, given below.

Amanta and purnimanta

Two branches of one family often keep the same shraddha a month apart. The two reckonings cut the month at different points, and the name of the dark fortnight moves with the cut.

Amanta

The month ends at the new moon. Amavasya is the last day, and the month opens on the first day of the bright fortnight.

Followed in Gujarat, Maharashtra, Goa, Karnataka, Andhra Pradesh and Telangana, and in the lunar reckoning used alongside the solar calendars of Tamil Nadu and Kerala.

Purnimanta

The month ends at the full moon. Purnima is the last day, and the month opens on the first day of the dark fortnight.

Followed across the north: Uttar Pradesh, Bihar, Madhya Pradesh, Rajasthan, Punjab, Haryana, Uttarakhand, Himachal Pradesh and Nepal.

Where they agree

On every bright fortnight. A day in the shukla paksha carries the same month name in both reckonings, which is why Ram Navami, Ganesh Chaturthi and every Purnima are named the same everywhere.

Where they differ

On every dark fortnight, and only in the name. Purnimanta gives a day in the krishna paksha the following month's name, and amanta gives it the current month's, so the purnimanta name runs one month ahead. The days themselves do not move by an hour.

Three examples

OccasionPurnimanta nameAmanta name
Pitru PakshaThe same sixteen days under two month names. A family that remembers its shraddha tithi as a month plus a tithi, and reads it in the other reckoning, lands a whole month out.Ashwin Krishna pakshaBhadrapada Krishna paksha
Krishna JanmashtamiThe easiest one to check at home. North and west India name the same night differently every year.Bhadrapada Krishna AshtamiShravana Krishna Ashtami
MahashivratriOne night, named for two different months. Everyone keeps it on the same night, and only the month name differs.Phalguna Krishna ChaturdashiMagha Krishna Chaturdashi

The reckoning at each ghat

Four of the six waters are in purnimanta regions and two in amanta regions. The month name printed beside a tithi follows the region.

  • Ganga, Har Ki Pauri, HaridwarPurnimanta
  • Triveni Sangam, Sangam, PrayagrajPurnimanta
  • Yamuna, Vishram Ghat, MathuraPurnimanta
  • Godavari, Ram Kund, NashikAmanta
  • Shipra, Ram Ghat, UjjainPurnimanta
  • Kaveri, Talakaveri, KodaguAmanta

Four reasons two households differ

If your uncle in Pune and your mother in Lucknow have never agreed on the day, one of these four is the reason. Both of them are usually right.

  • The month name

    Amanta and purnimanta give the same dark fortnight different month names, one month apart. A tithi remembered as a month plus a tithi, and read in the other reckoning, is a month out. This is the usual cause.

  • Where the day is cut

    The Hindu day runs from sunrise to sunrise. A death at two in the morning belongs to the panchang day that began at the previous dawn, not to the date on the hospital certificate. A family that converts the certificate date is often one day out from the start.

  • Which part of the day decides

    A tithi that spans two mornings has to be given to one of them. Ordinary observances take the tithi in force at sunrise, udaya vyapini. Shraddha takes the tithi in force at aparahna, the fourth of five equal parts of the daylight. Two panchangs applying the two rules name two different days, and both follow a rule.

  • Where sunrise is taken, and how it is computed

    A tithi ends at one instant everywhere on earth, but sunrise does not, so the day it lands on depends on the place the panchang is computed for. Drik siddhanta panchangs use observed positions and vakya panchangs use older tables, and at the edges the two can differ by a day. Ask which place and which system your family's panchang uses.

Finding the tithi from a date

You need a panchang for the year and place of the death, not a converter for this year. It takes about ten minutes.

  1. 01

    Write down the moment

    Write down the date, the time of day and the place of death. All three matter. If the death fell between midnight and sunrise, the panchang day is the previous calendar day.

  2. 02

    Read the tithi for that moment

    Look up a panchang for that place and year and read the tithi and paksha in force at that moment, for example krishna paksha, navami. That pair is what the family keeps, not the calendar date.

  3. 03

    Note which reckoning the panchang uses

    If the panchang gives a month name with the tithi, find out whether it is amanta or purnimanta, and write down both names if you can. A tithi recorded without its reckoning is the commonest way a shraddha day is lost between generations.

  4. 04

    Find that tithi in the fortnight

    In any later year, the day of Pitru Paksha that carries that tithi is the day. That is the whole rule, and it is why the calendar date moves and the observance does not. If the tithi falls outside the fortnight, or the death was by accident or violence, the named days above apply.

If your family already keeps a day, keep it. This page is for households that lost the thread.

Tithi, nakshatra, sunrise and the four windows are computed here with astronomy-engine and the Lahiri ayanamsa. On 11 September 2026 they were checked against Drik Panchang for Haridwar on eight days between September 2026 and March 2027: every tithi and nakshatra matched, every end time agreed within two minutes, and sunrise agreed within a minute. The method and the table are in docs/panchang-check.md. The calendar day an occasion falls on is still given as a month, and stays labelled provisional until each occasion's day rule has been checked the same way.
