Hijri-Gregorian Converter

The Hijri calendar is a lunar calendar of 12 months totaling 354 or 355 days, so it runs about 11 days shorter than the Gregorian year — Hijri dates shift roughly 11 days earlier each Gregorian year.

• Many countries (like Saudi Arabia) use the Umm al-Qura calendar based on astronomical observation, which can differ from the tabular calendar by a day.
• Ramadan and Eid dates are officially confirmed by moon sighting and may differ from any calculation.

Under the tabular calendar used here, 1 Ramadan 1448 AH falls on February 8, 2027 — the date many Muslim communities in the United States expect to begin fasting that year. Because the Hijri year is about 11 days shorter than the solar year, 1 Ramadan 1449 AH falls on January 28, 2028, nearly 11 days earlier.

• Try the reverse direction: enter 1448, Ramadan (month 9), day 1 and read back the Gregorian date.

• Hijri year number — the Islamic year, currently in the 1440s, which runs ahead of the Gregorian year because lunar years are shorter.
• Month name — one of the 12 lunar months, from Muharram to Dhu al-Hijjah.
• Accuracy note — this is an arithmetic (tabular) calendar; official dates in many regions follow moon sighting or the Umm al-Qura calendar and can differ by a day.
