Persian (Jalali) to Samaritan Date

Enter a date in the Persian (Jalali) calendar and the tool returns the equivalent date in the Samaritan calendar using the standard relationship between the two systems.

1. 1

   Step 1

   Enter the complete Persian (Jalali) date — day, month, and year.

2. 2

   Step 2

   We anchor each system's epoch, then convert day by day — Persian (Jalali): the Persian year ≈ 2026 − 621 = 1405; Samaritan: a 13th leap month lands 7 times in each 19-year cycle.

3. 3

   Step 3

   Read the exact Samaritan date: a year spanning 353–385 days, counted month by month.

• 1

  Persian (Jalali) and Samaritan dates do not map one-to-one — the two systems start from different epochs and count leap years differently, so enter the full Persian (Jalali) date and read the Samaritan equivalent instead of shifting the year by a fixed offset.

• 2

  Watch century boundaries and very old dates in the Persian (Jalali)–Samaritan system: historical calendars dropped or added days when they were adopted, which is invisible in daily use but material for long-range historical calculations here.

• 3

  Leap rules differ between the calendars behind Persian (Jalali)–Samaritan, so a span that looks like whole years in one system can land a day or two off in another; trust the converted result rather than a fixed mental offset.

• Reversing the direction is a silent trap: converting from the Samaritan calendar back to the Persian (Jalali) calendar needs the inverse relation, and off-by-one errors cluster at month boundaries where the systems disagree. Verify the round trip returns your original date.

• The Persian (Jalali) and Samaritan calendars differ in year length and leap pattern, so a fixed-day offset — 365, 354, any memorized constant — drifts the Samaritan date badly. Convert the complete date so both leap rules apply.
