Today marks the first full day of Ramadan in the U.S., starting a month of fasting, prayer, and introspection for Muslims worldwide.

Ramadan falls on the ninth month of the Islamic calendar, signified by the sighting of the crescent moon after the new moon. This celebrates when the first verses of the Quran were revealed to the Prophet Muhammad. Right now it’s a time of increased devotion for Muslims, taking place this year from March 11 to April 9.

During Ramadan, from sunrise to sunset Muslims around the world fast, practicing self-restraint and humbling themselves back to their basic necessities. After sunset, Muslims break their fast with an “iftar” meal. Traditionally, the meal begins with eating a date. Dinners and spending time with family are especially cherished during this time.

Muslims perform Taraweeh, night prayers, after breaking their fast. They are preferably performed communally in the mosque. The holy month of Ramadan promotes a time of community and charitable acts.

Before the sun rises, Muslims partake in “suhoor,” a pre-fasting meal. Following suhoor, they engage in the Fajr prayer, marking the beginning of fasting once more.

Ramadan concludes with Eid-al-Fitr celebrations worldwide. Eid takes place on April 9, in the U.S., but abroad celebrations can last up to three days. Family is at the core of the festivities.

A widely used and respectful greeting is, “Ramadan Mubarak,” conveying best wishes for a blessed Ramadan. Ramadan Mubarak!
