How is the Masikam tithi calculated?

The death civil day’s Aparāhṇa śrāddha tithi is the ancestral tithi. Each later month, Masikam falls on the civil day when that tithi prevails at Aparāhṇa and is the preferred (non-śūnya) observance day.

Is Masikam the same as the English death date every month?

No. Masikam follows the lunar tithi, so Gregorian dates shift each month. Always use a place-specific panchang, not a fixed day-of-month.

Enter the date of death and your place. Drikganita resolves the Aparāhṇa śrāddha tithi on that civil day, then lists the preferred monthly Masikam dates for the coming year.
