Which Countries Use the Hijri Calendar Today?
The Global Footprint of the Hijri Calendar: Tradition, Time, and Modern Governance
The Hijri calendar (Islamic or lunar calendar) is a timekeeping system consisting of 12 lunar months in a year of 354 or 355 days. Its epoch was established as the Islamic New Year in 622 CE, corresponding to the Hijra—the migration of the Prophet Muhammad and his followers from Mecca to Medina.
Official Civil Usage: The Case of Saudi Arabia
For centuries, the Hijri calendar governed trade, governance, and daily life across the Islamic world. In the modern era, however, most Muslim-majority nations transitioned to the Gregorian calendar for administrative, financial, and civil synchronization with global markets.
The notable exception is Saudi Arabia. For decades, the Saudi government utilized the Umm al-Qura calendar (a standardized version of the Hijri calendar) for all civil and governmental record-keeping. Though Saudi Arabia temporarily shifted its bureaucratic administrative departments to the Gregorian calendar in 2016 for economic efficiency, the Hijri calendar remains profoundly woven into the nation's cultural identity, official religious decrees, and educational systems.
Religious and Liturgical Usage Worldwide
In virtually every other Muslim-majority country—such as Egypt, Pakistan, Iran, Malaysia, Morocco, and Indonesia—the Gregorian calendar dictates civil life, while the Hijri calendar reigns supreme in the spiritual sphere. Governments rely on the lunar calendar to determine:
- Ramadan: The holy month of fasting.
- Eid al-Fitr and Eid al-Adha: The major Islamic holidays.
- Dhu al-Hijjah: The timing of the annual Hajj pilgrimage to Mecca.
Countries like Morocco and Oman maintain official committees dedicated to sighting the crescent moon each month, preserving an ancient observational tradition that connects modern citizens directly to the earliest days of Islam.
Linguistic and Cultural Nuance
Linguistically, the adoption of the Hijri calendar reflects a fascinating duality in the psychological perception of time across the Islamic world. While the Gregorian calendar organizes linear, globalized, and economic productivity, the Hijri calendar anchors believers in a cyclical, sacred time—a linguistic and cultural reminder of foundational historical roots established over fourteen centuries ago.
