A Message from Our Founder

When we started this Islamic calendar project in 2015,we saw many Muslims struggling to find consistent and trustworthy correct date in Saudi Arabia. Different Islamic calendar websites gave different answers for the same month, and people didn’t know which calendar system to follow—whether the moon sighting calendar, the calculated calendar, or regional variations.

we wanted to create something clear and dependable—a single authoritative source that follows the official Umm al-Qura system used in Saudi Arabia and trusted by millions of Muslims for determining Ramadan dates, Eid dates, and other Islamic occasions.

This website exists to serve you and the global Muslim community. Whether you’re planning ahead for Ramadan fasting, checking the date of Eid al-Fitr or Eid al-Adha, scheduling Hajj pilgrimage dates, or simply staying connected to the Islamic lunar calendar in your daily routine, we’re here to make that easier. May Allah accept this humble effort and benefit the Ummah.
