The first day of Ramadan is not given a special, unique name in mainstream Islamic practice; it is simply called the first day of Ramadan, often referred to in phrases like “the beginning of Ramadan” or “the first fast of Ramadan.”

Muslims mark this day after the new crescent moon is sighted, which signals the start of the ninth month of the Islamic calendar, Ramadan. From that first dawn, fasting from sunrise to sunset becomes obligatory for eligible adult Muslims, and many people treat it as a spiritual “reset,” focusing on intention, extra prayer, and recitation of the Quran.
