About September in the Religious Calendars

September 2025 corresponds to portions of multiple lunar months in both the Islamic Hijri calendar and the Hindu lunar calendar. Because both lunar systems run shorter than the Gregorian solar year — the Hijri year by approximately eleven days and the Hindu lunar year is corrected through periodic intercalary months — the festivals listed above shift their Gregorian month-of-occurrence year over year. A holiday that falls in September this year may fall in the preceding or following Gregorian month next year, and may have already moved by several days even within 2025. The Islamic Hijri month or months overlapping September 2025 can be browsed through our calendar conversion tool, and the corresponding Hindu lunar months are catalogued in our Hindu month overview series. For the full chronological listing of all 23 Islamic and Hindu observances in 2025, see our 2025 year overview. To plan a multi-year commemoration, schedule, or recurring event, our Islamic festival index and Hindu festival index provide cross-year date tables for every holiday HijriHub covers.
