Hijri and Gregorian Calendar Differences
The Gregorian calendar is a solar calendar based on the Earth's orbit around the Sun. The Hijri calendar is a lunar calendar based on lunar months.
Because a lunar year is shorter than a Gregorian solar year, Hijri months and dates move through different seasons over time. This is why Islamic occasions such as Ramadan and Hajj do not occur on the same Gregorian dates every year.
