Ramadan Calendar
Ramadan Calendar Guide
The Ramadan calendar is based on lunar months. Use this guide to understand how the start of Ramadan changes each year and how to prepare for fasting.
How Ramadan dates are determined
Ramadan begins with the sighting of the new moon, which means dates shift earlier by about 10 to 11 days each Gregorian year. This makes Ramadan a mobile month across the solar calendar.
Preparing for Ramadan
Use date tools to estimate the expected Ramadan window, plan meals, and coordinate travel. Sharing your Ramadan calendar with family helps everyone stay aligned.
