Persian (Jalali) Day of the Week Finder

Enter the date values and the tool computes the result for the persian calendar system.

1. 1

   Step 1

   Enter your date in the Persian (Jalali) calendar: day, month, and year.

2. 2

   Step 2

   We apply the Persian (Jalali) epoch and leap rules — the Persian year ≈ 2026 − 621 = 1405.

3. 3

   Step 3

   Read the result exact to the day — Persian (Jalali) leap years (365–366 days) applied automatically.

• 1

  This Persian (Jalali) Day of the Week Finder follows Persian (Jalali) calendar rules — its own epoch, month lengths, and leap years — so the result can differ from a Gregorian-based calculation of the same date; treat the calendar system as part of the input.

• 2

  Enter the Persian (Jalali) 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 Persian (Jalali) date goes into a booking or a flight, re-enter it in a second tool as a cross-check — pages like Persian (Jalali) Day of the Week Finder apply fixed rules and cannot warn about a transposed input digit.

• Year-length drift compounds quietly: a Persian (Jalali) year averages about 365 days, so the same month-day is a different day count every year and a weekday lookup from one year cannot be scaled to another. Recompute across the exact years involved.

• Epochs are not interchangeable: every calendar owns its day zero, and year arithmetic borrowed across systems shifts a weekday lookup by years. Confirm the persian (jalali) epoch (the Persian year ≈ 2026 − 621 = 1405) before comparing dates.
