Guide

Convert Persian Solar Hijri and Gregorian dates

This Persian Date Converter changes Gregorian calendar dates into Persian Solar Hijri dates and converts Persian calendar input back into Gregorian dates. It is useful for civil date lookup, comparing records that use different calendars, and checking a Persian date before entering it into another system.

Gregorian input uses YYYY-MM-DD through the date field, and Persian input uses the same YYYY-MM-DD structure in the text field. The result includes the normalized Persian or Gregorian date, the Persian month name when relevant, and the weekday calculated from the Gregorian timestamp.

The page uses the ICU persian calendar implementation. That keeps the conversion deterministic for modern Solar Hijri date lookup and avoids mixing the Persian calendar with unrelated Hijri lunar calendars, which use a different month structure and year length.

What it handles

Solar Hijri conversion coverage

The converter handles the modern Persian Solar Hijri calendar as exposed by ICU. It does not attempt to translate between Persian month names entered as free text; instead, it keeps the input numeric so the same date can be validated and converted back predictably.

Both directions use the same calendar engine. That matters because Solar Hijri leap-year behavior affects the final month of the year, and the converter should reject impossible dates rather than rolling them into a different valid day.

Gregorian to Persian

Enter a Gregorian date and return the matching Persian year, month, day, month name, and weekday.

Persian to Gregorian

Enter a Persian Solar Hijri date in YYYY-MM-DD format and convert it back into Gregorian form.

Round-trip validation

Invalid Persian month and day combinations are rejected instead of being silently normalized into a different date.

How to use

Choose the Persian conversion direction

Pick the mode based on the source calendar of the date you already know. The Gregorian side uses the site-wide Gregorian parser, while the Persian side accepts a numeric Solar Hijri date and validates it through ICU.

When entering Persian dates, keep leading zeroes for the month and day. A value such as 1405-04-09 is easier to parse, compare, and copy than a mixed text date with a month name.

1

Use Solar Hijri terms

This page is for the Persian Solar Hijri calendar, not the Islamic Hijri lunar calendar. For civil Hijri dates, use the Islamic Date Converter instead.

Examples

Reference conversions from the local implementation

These examples are verified against the local converter functions. They show the exact numeric format used in the form and demonstrate that the same date can be converted in either direction without changing calendar rules.

Gregorian date to Persian date

2026-06-30 -> 1405-04-09

The Gregorian date 2026-06-30 converts to Tir 9, 1405 AP in the ICU persian calendar.

Persian date to Gregorian date

1405-04-09 -> 2026-06-30

The Persian input 1405-04-09 converts back to Gregorian 2026-06-30.

FAQ

Persian date conversion notes

Persian date conversion is often confused with Islamic Hijri conversion because both may be called Hijri in different contexts. The answers below keep the page tied to Solar Hijri behavior and the actual input format accepted by the form.

Is the Persian calendar the same as the Hijri calendar?

No. This converter is for the Solar Hijri Persian calendar. The Islamic Date Converter handles the civil Hijri lunar calendar.

What Persian input format is accepted?

Use YYYY-MM-DD, for example 1405-04-09. The converter checks that the resulting ICU date still matches the year, month, and day you entered.

Does this page calculate local sunset changes?

No. It converts civil calendar dates at midnight UTC using ICU calendar fields. It is intended for date lookup, not local astronomical event timing.

The PHP Intl calendar object used by this page is backed by ICU. ICU documents calendar identifiers and behavior for non-Gregorian calendars, including the persian calendar identifier used by the converter.
