Persian (Jalali) Age Calculator

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 walk the real Persian (Jalali) calendar — a solar year of 365 days (366 in leap years) — instead of a flat 30-day-month average.

3. 3

   Step 3

   The output breaks down years, months, and days on real Persian (Jalali) lengths.

• 1

  This Persian (Jalali) Age 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

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

• 3

  Time zones can move a Persian (Jalali) 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.

• Feb 29 birthdays break naive age math: depending on jurisdiction, a leap-day birth ages on Feb 28 or Mar 1 in common years. An age computed under the Persian (Jalali) calendar with plain day division drifts from the legal figure.

• Reusing a memorized constant — fixed day counts, epoch offsets — instead of the Persian (Jalali) rules drifts silently across years because leap days accumulate differently per system. Recompute with the tool rather than adding offsets by hand.
