The Gregorian calendar and the Islamic calendar are two different ways to measure time. Most of the world uses the Gregorian calendar for daily life and business. Muslims around the world use the Islamic calendar to know when holy days happen. Here is how these two calendars compare. ☀️ Sun vs. 🌙 Moon The biggest difference is what they follow in the sky.
Gregorian calendar: This is a solar calendar. It tracks the Earth’s movement around the sun.
Islamic calendar: This is a lunar calendar. It tracks the phases of the moon. 📅 Length of the Year
Because they follow different things in the sky, their years have different lengths.
Gregorian year: It has 365 days in a normal year. Every four years, it gets a leap day to make it 366 days.
Islamic year: It has 354 or 355 days. This makes it about 11 days shorter than the solar year. 🍁 Changing Seasons
The difference in year length changes how we see the seasons.
Gregorian dates: The dates stay in the same season every year. For example, January is always in the winter for the northern part of the world.
Islamic dates: The dates move backward through the seasons. Holy months like Ramadan move by about 11 days each year. Ramadan can happen in the hot summer or the cold winter over time. 🏁 The Starting Point
Both calendars started counting years from a major historical event.
Gregorian calendar: It starts from the estimated birth of Jesus Christ. Years are marked as AD or CE.
Islamic calendar: It starts from the Hijrah. This was when Prophet Muhammad moved from Mecca to Medina. Years are marked as AH. 🕒 When the Day Begins Even the exact time a new day starts is different. Gregorian day: A new day starts at midnight. Islamic day: A new day starts at sunset.
