This Disclaimer governs your use of the Event Hijri website and our tools (Prayer Times Calculator, Calendar Converters).
All technical information about historical events, Islamic months, and times provided on this site are for educational and planning purposes. We strive to provide highly accurate Hijri constraints based on established astronomical calculations, but human errors or regional calculation variations may occur.
Our daily prayer schedules use specialized regional formulas (e.g. MWL, ISNA, Umm al-Qura). Because atmospheric variations define true dawn and dusk, a calculable variance of 1-3 minutes is possible. Event Hijri will not bear responsibility for fasting or prayer mistakes; observing your local mosque schedule is always recommended.
Global Hijri calendars mathematically predict the visibility of the new moon. True Islamic dates for Ramadan, Eid al-Fitr, and Eid al-Adha are established through physical crescent moon sightings. Therefore, you must abide by the official declarations of your local or national religious authorities.
