Persian (Jalali) Weeks Between Dates

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

1. 1

   Step 1

   Enter both dates in full under the Persian (Jalali) calendar: day, month, and year each.

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) Weeks Between Dates 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

  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) Weeks Between Dates apply fixed rules and cannot warn about a transposed input digit.

• 3

  Watch century boundaries and very old dates in the Persian (Jalali) 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.

• 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 weeks-between count from one year cannot be scaled to another. Recompute across the exact years involved.

• Leap rules differ between the Persian (Jalali) calendar and the simplified school shortcut, so filters like “divisible by 4” are not enough. Let the tool apply the persian (jalali) intercalation rule to the actual year you entered.
