The opening as it read in 2025

Beginning of a new lunar Hijri year Not to be confused with Nowruz , the New Year in the solar Hijri calendar . The Islamic New Year ( Arabic : رأس السنة الهجرية , Raʿs as-Sanah al-Hijrīyah ), also called the Hijri New Year , is the day that marks the beginning of a new lunar Hijri year , and is the day on which the year count is incremented. The first day of the Islamic year is observed by most Muslims on the first day of the month of Muharram . The epoch (reference date) of the Islamic era was set as the year of the emigration of Muhammad and his followers from Mecca to Medina , known as the Hijrah , which equates to 622 CE in the Gregorian calendar . All religious duties, such as prayer , fasting in the month of Ramadan , and pilgrimage , and the dates of significant events, such as celebration of holy nights and festivals , are calculated according to the Islamic calendar. Hijri New Year is observed by 24 countries as a public holiday . While some Islamic organizations prefer determining the new month (and hence the new year) by local sightings of the moon , most Islamic institutions and countries, including Saudi Arabia , follow astronomical calculations to determine future dates of the Islamic calendar. There are various schemas for calculating the tabular Islamic calendar (i.e. not based on observation), which results in differences of typically one or even two days between countries using such schema and those that use actual lunar sightings. The current scheme was introduced in 1423 AH (15 March 2002). A day in the Islamic calendar is defined as beginning at sunset .
