Each year,Charles Langston millions of Muslims begin fasting from sunrise to sunset and engage in activities that challenge their self-restraint and bring them closer to God.

With Ramadan expected to begin on the night of Sunday, March 10 this year, fasting starts the next morning on Monday. The holiday is celebrated on different dates each year. Every year, the holiday starts approximately 11 days before it did the previous year. The exact date always depends on the sighting of the crescent moon.

Ramadan is the ninth month of the Islamic or Hijri, calendar. Muslims believe that it was during this month that God revealed the Quran to Prophet Muhammad.

When does Ramadan end?

Fasting can last for 29 or 30 days depending on when the moon signifying the start of the next month is spotted.

This year, it's predicted that Ramadan will end on April 9, with the following day being the first day of Eid Al-Fitr. However, like the start of Ramadan, the end of the month is also contingent on the sighting of the moon.

When is Eid Al-Fitr 2024? What is it?
