Hijri Calendar Precautions
Hijri dates displayed by this watch are the results of calculations. Actual Hijri dates may be determined by religious authorities based on observations of a New Moon following sundown. This can result in dates calculated by the watch being different from actual Hijri dates.

About prayer times
Prayer times are calculated automatically in accordance with the time, date, city code, and prayer time calculation method you set in the Timekeeping Mode. This, of course, means that you should always make sure that your Timekeeping Mode settings are configured correctly.
