The year 2030 is expected to bring a rare calendar phenomenon: Ramadan is set to occur twice within the same Gregorian year. This happens because the Hijri calendar follows the lunar cycle, while the Gregorian calendar is based on the solar cycle.
Since a lunar year is around 10 to 11 days shorter than a solar year, Islamic months move earlier each year on the Gregorian calendar. That is why Ramadan does not stay in the same season or month, but continues rotating over time through the full solar calendar.
Based on astronomical calculations, the first Ramadan of 2030 is expected to begin around January 5, 2030. Later in the same year, the lunar cycle is projected to bring a second Ramadan starting around December 26, 2030. This means observers would complete one full Ramadan early in the year and then begin another one in the final days of December.
In practical terms, that would mean about 30 days of fasting at the start of 2030, followed by around 6 more days at the end of December. The rest of that second Ramadan would then continue into January 2031, completing the month across two different Gregorian years.
This is not a yearly event, but a rare alignment that usually appears once every 32 to 33 years. Similar cases were recorded in 1900, 1932, 1964, and 1997, while astronomers expect the pattern to happen again around 2062 to 2063. The shift reflects how the Hijri calendar gradually moves through every season and month over the decades.
