How to use this calculator
Choose the method and direction, then enter the date. The method stays visible in the report and shared setup.
Browser ICU supplies the selected calendar. Gregorian coverage is 1900-2100; Umm al-Qura is additionally limited to AH 1300-1600. Conversion labels civil dates and does not resolve local sighting decisions or sunset times.
A worked example
On November 4, 2026, the tabular civil method gives 1448-05-23; Umm al-Qura gives 1448-05-24.
Why can two methods differ by a day?
They use different calendar rules and reference data. A local religious calendar may also follow sighting decisions. Select the convention you need.

Which calendar and years are supported?
Gregorian input coverage is 1900-2100 unless the method states a narrower range. Results explain calendar conventions and local date boundaries. Astronomy uses a level horizon at sea level. CSV, print and copy retain the result rules; calendar files contain only calculated events. Nothing is scheduled automatically.
