Yazidi to Coptic Date Converter

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

2. 2

   Step 2

   We apply both systems' rules: a Yazidi year runs about 365 days against the Coptic 365 (≈0 days apart each year).

3. 3

   Step 3

   The result shows the correct Coptic day, with Coptic leap years applied date by date.

• 1

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

• 2

  For deadlines tied to authorities or contracts, confirm which calendar the deadline officially uses before converting it here — a Yazidi–Coptic date read in the wrong system can be off by days or even a full year.

• 3

  Enter the Yazidi–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.

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

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