Terms of Service

Using this site

Muslim Calendar is a free reference tool for Hijri dates, prayer times, and Islamic event dates. You're welcome to use it for personal, non-commercial reference. Please don't scrape, republish, or redistribute the site's content at scale without permission.

Accuracy of dates and times

Hijri dates are calculated using the tabular Islamic calendar, a mathematical estimate, not a moon-sighting confirmation. Prayer times are computed from standard astronomical formulas. Both can differ slightly from your local mosque or Islamic authority. For religious observance — including the start of Ramadan, Eid, or daily prayers — always defer to your local moon-sighting committee or mosque.

No warranty

This site is provided "as is," without warranties of any kind. We work to keep dates and times accurate but don't guarantee the site will be error-free, uninterrupted, or fit for any particular purpose.

Limitation of liability

To the extent permitted by law, Muslim Calendar and its operators aren't liable for any loss or inconvenience arising from reliance on information shown on this site.

External links and services

This site uses the Aladhan API for prayer time calculations. We're not responsible for the availability or accuracy of third-party services we link to or rely on.

Changes to these terms

We may update these terms from time to time. Continued use of the site after changes means you accept the updated terms.
