In 2039, Muslims are expected to witness a rare calendar occurrence: three Eid celebrations and two Hajj seasons within the same Gregorian calendar year.
This unusual alignment occurs because the Islamic Hijri calendar is lunar, with a year of approximately 354 days, while the Gregorian calendar is solar, with 365 days. As a result, Islamic dates shift approximately 10–11 days earlier each year.
According to current astronomical calculations, the expected timeline for 2039 is:
• January 5–6, 2039 — Hajj Season & Eid al-Adha
Dhul-Hijjah 1460 AH
• October 19, 2039 — Eid al-Fitr
Shawwal 1461 AH
• December 25–26, 2039 — Hajj Season & Eid al-Adha
Dhul-Hijjah 1461 AH
This rare alignment is possible because the shorter Islamic lunar year allows two separate Hijri years—and therefore two Dhul-Hijjah periods—to fall within the same Gregorian year.
