Eid al-Fitr is celebrated by Muslims worldwide because it marks the end of the month-long dawn-to-sunset fasting of Ramadan.

Ramadan, is the ninth month of the Islamic calendar, observed by Muslims worldwide as a month of fasting (sawm), prayer (salah), reflection, and community. The annual observance of Ramadan is regarded as one of the Five Pillars of Islam and lasts twenty-nine to thirty days, from one sighting of the crescent moon to the next.

The holiday of Eid al-Fitr which marks the end of Ramadan and the beginning of Shawwal, the next lunar month, is declared after a crescent new moon has been sighted or after completion of thirty days of fasting if no sighting of the moon is possible. Eid celebrates the return to a more natural disposition of eating, drinking.

Eid al-Adha or the Feast of Sacrifice is the second of the two main holidays celebrated in Islam. Eid al-Adha is celebrated on the 10th day of Dhu al-Hijjah, the twelfth and final month of the Islamic calendar.
