The Saudi Supreme Court announced that Tuesday, April 9, 2024, marks the beginning of the new Islamic year, 1445 AH, according to an official statement released on Sunday. This determination follows the confirmation of the moon’s sighting by the Saudi Committee for the Observation of the Moon, a body responsible for validating lunar calendar dates in the kingdom.
What is the Islamic calendar and how is its start determined?

The Islamic calendar, also known as the Hijri calendar, is a lunar calendar consisting of 12 months, each lasting 29 or 30 days. Unlike the Gregorian solar calendar, its start is contingent on the visibility of the new moon. According to the Saudi Committee for the Observation of the Moon, the new year began after astronomers and religious authorities confirmed the moon’s sighting on Sunday evening, April 7, 2024.
How does Saudi Arabia’s decision align with other Muslim-majority regions?
While Saudi Arabia’s announcement sets the official start of the Islamic year for the kingdom, other Muslim-majority countries may observe the new year on different dates. For example, Pakistan and Indonesia often rely on local moon sighting committees, which can lead to variations in the calendar. This divergence highlights the decentralized nature of lunar calendar calculations, as noted by the Islamic Fiqh Council in 2023.
Why does the Islamic year matter to Muslims globally?
The start of the Islamic year holds religious significance, as it marks the anniversary of the Prophet Muhammad’s migration (Hijra) from Mecca to Medina in 622 CE. The new year also influences the timing of religious observances, such as Ramadan and Eid al-Fitr, which are calculated based on the lunar cycle. According to the Organization of Islamic Cooperation, the 1445 AH year will see Ramadan begin in late March 2024, though exact dates will depend on regional moon sightings.
What are the implications of this announcement for Saudi Arabia?
The Saudi Supreme Court’s declaration reinforces the kingdom’s role as a central authority in Islamic calendar matters. Historically, Saudi Arabia has been a key player in resolving discrepancies in lunar calendar calculations, particularly through its use of advanced astronomical technology. The 2024 announcement also aligns with the government’s broader efforts to modernize religious practices while maintaining traditional interpretations, as outlined in a 2022 white paper on Islamic affairs.
For now, the Islamic year 1445 AH is officially underway in Saudi Arabia, with religious and cultural activities set to begin on the confirmed date. Global Muslim communities will continue to monitor local moon sightings to align their calendars accordingly.
