Calendar

The Solar Hijri calendar, also known as the Shamsi Hijri calendar, is the official calendar of Iran, commencing on the March equinox (Nowruz). As it is determined by astronomical factors, the new year may vary from year to year, in contrast to the Gregorian calendar, which is fixed. The Solar Hijri calendar comprises either 365 or 366 days per year.

Juggling three calendars. Understanding and managing multiple calendars can be challenging for foreigners, as they must now navigate between the Gregorian, the Islamic Lunar Hijri, and the Shamsi Hijri calendars. In order to minimise the potential for confusion and errors, it is advisable to download a Persian calendar app on one’s mobile device. These apps typically provide access to all three calendars and a conversion tool which easily converts dates from one calendar to the other. Popular apps include Persian Calendar for Android and iPersia for iOS.
