Hatem Ouda, chairman of Egypt's National Research Institute of Astronomy and Geophysics, has announced that the holy fasting month of Ramadan would officially begin this year on 20 July and end on 20 August, according to astronomical and mathematical calculations.
According to institute officials, this year's Eid El-Fitr will fall on 21 August.
Ramadan is the ninth month of the Islamic lunar calendar, during which Muslims abstain from drinking and eating during the day before breaking their fast at sunset.
Muslim scholars and astronomers often disagree on what day the month of Ramadan begins on. Many depend on seeing the moon with their own eyes to determine the beginning of the month based on their geographical location.
