Site Methodology

The site uses the Umm al-Qura calendar as its primary Hijri reference.

That reference powers the today page, date conversion, age calculation, event countdowns, and month archive pages.

The site resolves the current date against Makkah time so “today” does not drift with whatever timezone the server happens to be running in.

The civil date changes at midnight, while religious nights begin at local sunset. A sighting correction shifts Hijri dates only; weekdays, Gregorian dates, and the moon phase remain tied to the actual instant. Month archives are explicitly unadjusted.

Some countries follow an official calculated calendar, while others wait for local moon-sighting confirmation or a religious authority announcement.

Because of that policy difference, Ramadan, Shawwal, and Dhul Hijjah can begin one day earlier or later in some places.

The main pages render explanatory content directly in HTML at request time so users and search engines can understand the page without depending entirely on JavaScript.

Interactive tools such as the date converter and age calculator then continue working in the browser without requiring a separate external calculation service.

The moon phase shown on the site is computed from the mean synodic cycle (about 29.53 days) measured from a known reference new moon.

This is an approximation: because the moon's actual motion is not perfectly uniform, the displayed phase can differ from the true new or full moon by up to about one day. It is intended as a visual reference, not a substitute for precise astronomical computation or official crescent sighting.

Conversion is supported for 1300–1600 AH. Age is measured in completed calendar months; missing anniversary days use the last day of the target month, including February 29 in a non-leap year.

If you need a final official result for worship announcements or formal paperwork, the final authority is the relevant local institution or the original document source.
