The Islamic calendar (Hijri calendar) is based on the moon. Therefore, Islamic months shift each year relative to the Gregorian calendar. For many Muslims, the Hijri date is important for periods such as Ramadan, Dhul Hijjah, and holidays like Eid.

What is the Hijri calendar?

The Hijri calendar has 12 lunar months. A month begins with the sighting of the new moon (or according to a calculation method). Therefore, the start of a month can sometimes vary by one day depending on the country or method.

Why is this important?

• Better planning around Islamic months and moments and recognizing important days in time.
• Increased awareness around prayer, fasting and worship.
