Era in the Islamic calendar This article is about the Islamic era. [ refresh ] The Hijri year ( Arabic : سنة هجرية , romanized : sanat hijriyya ) or era ( Arabic : التقويم الهجري , romanized : at-taqwīm al-hijrī ) is the era used in the Islamic lunar calendar . It begins its count from the Islamic New Year in which Muhammad and his followers migrated from Mecca to Yathrib (now Medina ) in 622 CE. This event, known as the Hijrah , is commemorated in Islam for its role in the founding of the first Muslim community ( ummah ). Currently, the Hijri year is AH 1447 . Please note: the lunar Hijri date, calculated according to the lunar Hijri calendar, is different from the solar Hijri date, calculated according to the solar Hijri calendar or Persian calendar, which is only being officially used in Iran ("Persia"). In the West, the lunar Hijri era is most commonly denoted as AH ( Latin : Anno Hegirae , / ˈ æ n oʊ ˈ h ɛ dʒ ɪ r iː / , lit. ' in the year of the Hijra ' ) in parallel with the Christian / Common (AD/CE) and Jewish eras (AM) and can similarly be placed before (preferably) or after the date. In predominantly Muslim countries , it is also commonly abbreviated H ("Hijra") from its Arabic abbreviation hāʾ ( هـ ). Years prior to AH 1 are reckoned in English as BH ("Before the Hijra"), which should follow the date. A year in the Islamic lunar calendar consists of twelve lunar months and has only 354 or 355 days in its year. Consequently, its New Year's Day occurs ten days earlier each year relative to the Gregorian calendar . The year 2026 CE corresponds to the Islamic years AH 1447 – 1448; AH 1446 corresponds to 2024 – 2025 in the Common Era.
