Why Mahalaya Amavasya matters
Mahalaya (Sarva Pitru) Amavasya is the last day of Pitru Paksha and the foremost shraddha day of the year. Ancestors whose death tithi is unknown — or was missed earlier in the fortnight — are remembered with tarpan and pind daan on this day.
How the date is fixed
Mahalaya Amavasya is the Amavasya that closes Pitru Paksha (Ashwina, purnimanta). A lunar month is shorter than a solar one, so the Gregorian date moves every year. The observance day follows which tithi is running at sunrise, which is why regional panchangs can differ by a day.
