What is the Jalali calendar?

The Jalali calendar is the official solar calendar of Iran and Afghanistan. It was reformed by the mathematician Omar Khayyam in 1079 CE and begins each year precisely at the spring equinox (Nowruz). It is the most accurate solar calendar ever devised, with a leap year error of one day in 3,770 years.

What is the difference between Jalali and Shamsi calendar?

Jalali and Shamsi refer to the same calendar system. Jalali honors Sultan Jalal al-Din Malik Shah who commissioned Omar Khayyam's 1079 CE reform. Shamsi comes from the Arabic word for 'sun', reflecting its solar nature. Iranian calendar and Solar Hijri calendar are also names for the same system.

What year is it in the Persian calendar?

The current Persian (Jalali/Shamsi) year is 1405. The Persian year begins at Nowruz — the spring equinox — so the Persian year 1405 corresponds to the Gregorian year range Mar 20, 2026 – Mar 19, 2027.

Can I convert Persian date to Gregorian?

Yes. Select "Persian → Gregorian" at the top of the converter, enter the Jalali year, month, and day, and the Gregorian equivalent appears instantly. The converter handles full bidirectional conversion between Persian (Shamsi/Jalali) and Gregorian calendars.

How accurate is the Persian calendar?

The Persian calendar is the most accurate solar calendar in use. Omar Khayyam's 1079 CE reform achieved a leap year error of just one day in 3,770 years — more accurate than the Gregorian calendar, which has a drift of one day in 3,300 years. The Persian calendar achieves this through a sophisticated 2,820-year cycle.

Today is 24 Khordad 1405 in the Persian calendar — June 14, 2026 in Gregorian.

How This Conversion Works

The Persian calendar begins each year at the vernal equinox — the astronomical moment of spring. Converting from Gregorian to Jalali (or Shamsi to Miladi) requires accounting for the 2,820-year cycle Omar Khayyam devised in 1079 CE — far more precise than the Gregorian 400-year Leap cycle.

The Solar Hijri (Shamsi) calendar counts years from the Hijra in 622 CE but follows the solar year — unlike the Islamic lunar Hijri calendar. This makes the Iranian calendar converter unique: it aligns perfectly with the seasons while carrying historical continuity. The result is a calendar that the Gregorian system, introduced 500 years after Khayyam's reform, still cannot match in astronomical accuracy.
