Yazidi to Samaritan Date Converter

Enter a date in the Yazidi 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 Yazidi date — day, month, and year.

2. 2

   Step 2

   We anchor each system's epoch, then convert day by day — Yazidi: epoch 631 CE (Yazidi year ≈ 2026 − 630 = 1396); 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.

  Yazidi 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 Yazidi date and read the Samaritan equivalent instead of shifting the year by a fixed offset.

• 2

  Time zones can move a Yazidi–Samaritan date by a full day around midnight: today in one zone is still yesterday or tomorrow in another, so anchor the calculation to the zone your event actually follows before you enter anything.

• 3

  Watch century boundaries and very old dates in the Yazidi–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.

• Epoch offsets are pair-specific: day zero of Yazidi and of Samaritan are different dates, and constants borrowed from another calendar pair are silently wrong by days or years. Use the Yazidi → Samaritan relation itself, not a remembered number.

• Reversing the direction is a silent trap: converting from the Samaritan calendar back to the Yazidi 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.
