Hijri dates

The Islamic calendar is lunar. Calendar conversions and predicted dates can be useful planning tools, but local observance may differ depending on regional practice and moon-sighting decisions.

For religious observances that depend on an officially declared date, follow the trusted authority or mosque relevant to your community.

What IHSAYA can provide

Calendar information can help users understand the current Hijri date and prepare for important periods while keeping the distinction between calculated information and local religious determination clear.
