2030 Will Bring Two Ramadans in One Year—Here's Why It's Happening

In 2030, Muslims around the world will observe Ramadan twice in the same Gregorian year. This rare event occurs because the Islamic lunar calendar is shorter than the solar-based Gregorian one. The first fasting period, ramadan 2025, will begin on January 5, with a second starting on December 26.

The Islamic calendar follows lunar cycles, lasting about 354 days—roughly 11 days shorter than a solar year. This difference means Ramadan shifts earlier each Gregorian year. By 2030, it will fall twice, once in January and again in December.

The start of Ramadan depends on the sighting of the crescent moon. Currently, no Islamic country uses scientific calculations alone; all rely on human observation. For example, in 2026, moon sightings on February 18 confirmed Ramadan would begin the next day.

Daily fasting hours vary greatly depending on the season. In winter, fasts are shorter, while summer can require over 17 hours without food or drink. In 2030, Muslims will fast for a total of 36 days—30 in January and 6 in December.

This double occurrence last happened in 1997 and won't repeat until 2063.

The two Ramadan periods in 2030 will create a unique situation for Muslims globally. Fasting schedules will differ significantly between January and December due to seasonal changes. The event highlights the ongoing reliance on traditional moon sighting rather than scientific methods for determining the holy month's start.
