march 21 : significant historical events around the world Let’s learn about Significant historical events around the world. March 21 is the 80th day of the year, but in a leap year, it’s the 81st day. The Persian calendar is based on the solar calendar of ancient Egypt, which was introduced to Iran by Darius I of the Achaemenid dynasty around 500 BC. The calendar has 12 months of 30 days, plus an additional 5 days for a total of 365 days. However, in order to match the seasons, a leap year was established every four years to compensate for the difference in seasons. This structure results in a new year starting each year based on the vernal equinox (nor’easter). The vernal equinox usually occurs on March 20 or 21, so sometimes the new year will start on March 20 or 21.

Conclusion
As Persia was absorbed into Islamic culture, the Persian calendar became based on the Hegira calendar used in the Islamic world. This change was officially confirmed by a decision of the Persian National Assembly on March 31, 1925, during which the calendar was revised to make it compatible with the Gregorian calendar. Afghanistan only fully adopted this calendar system in 1957, and it is used jointly by Iran and Afghanistan to this day. This is due to the close historical and cultural ties between Iran and Afghanistan, making it natural for these calendars to be used in common.
