Baha'i to Gregorian Date Converter

Enter a date in the Baha'i calendar and the tool returns the equivalent date in the Gregorian calendar using the standard relationship between the two systems.

1. 1

   Step 1

   Enter the complete Baha'i date — day, month, and year.

2. 2

   Step 2

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

3. 3

   Step 3

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

• 1

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

• 2

  Watch century boundaries and very old dates in the Baha'i–Gregorian 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

  Time zones can move a Baha'i–Gregorian 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.

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

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