How to use this tool
- Choose the input calendar and enter a date as YYYY-MM-DD.
- Both calendars are shown. Switching the input calendar preserves the same day when input is valid.
- We use the ICU 78.1 Umm al-Qura table for 1300–1600 AH: 1882-11-12 to 2174-11-25. Dates outside this range are rejected, without another calendar method. Software validation against ICU is not government certification.

A few useful answers
How are day boundaries and conversion defined?
Conversions use civil dates without a time: no sunset rollover or dependency on your device timezone. Today uses Riyadh time. Religious moon-sighting determinations can differ from calculated calendars.
Are my inputs stored?
