Samaritan to Coptic Date Converter

Enter a date in the Samaritan calendar and the tool returns the equivalent date in the Coptic calendar using the standard relationship between the two systems.

1. 1

   Step 1

   Enter the complete Samaritan date — day, month, and year.

2. 2

   Step 2

   We anchor each system's epoch, then convert day by day — Samaritan: a 13th leap month lands 7 times in each 19-year cycle; Coptic: the Coptic year ≈ 2026 − 284 (it begins ≈ 11 September).

3. 3

   Step 3

   Read the exact Coptic date: a year spanning 365–366 days, counted month by month.

• 1

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

• 2

  Enter the Samaritan–Coptic dates in YYYY-MM-DD format to avoid ambiguity — some conventions read 03/04 as March fourth and others as April third, and a swapped month and day silently shifts every result this page derives.

• 3

  Before a Samaritan–Coptic date goes into a booking or a flight, re-enter it in a second tool as a cross-check — pages like Samaritan to Coptic Date Converter apply fixed rules and cannot warn about a transposed input digit.

• Anniversaries do not survive conversion unchanged: a Samaritan date maps to a fixed Coptic date, but next year's Samaritan anniversary lands on a different Coptic date. Reconvert each occurrence instead of adding one year to the last result.

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