LOS ANGELES — The Islamic holy month of Ramadan, commemorating the first revelation of the Quran to the Prophet Muhammad, will begin Friday evening upon the sighting of the moon, with fasting beginning on Saturday.

Ramadan is the ninth month of the Islamic lunar calendar, during which Muslim adults fast from dawn until dusk each day, unless they are ill, pregnant, diabetic, breastfeeding or traveling.

Fasting is one of the "five pillars" of Islam, along with the declaration of faith, daily prayers, charity and pilgrimage to Mecca.

During Ramadan Muslims engage in increased prayer and charity, both financially and feeding and supporting the local unhoused population. Individuals and organizations typically host iftars, the meal eaten when breaking the fast, to benefit those in need.

The end of Ramadan, Eid al-Fitr, which will fall on March 30, according to Fiqh Council of North America, based on calculations determining the lunar calendar, will be marked by communal prayers called Salat al-Eid.

The Anaheim Union High School District and Garden Grove Unified School District will provide free Ramadan meal kits for fasting Muslim students beginning Monday.
