Ramadan is the ninth month of the Islamic lunar calendar and the holiest period in the Muslim year. It is observed by fasting from sunrise to sunset, prayer, Quran recitation, self-reflection, and charitable giving, while also cultivating self-control, gratitude, and compassion. Roughly 1.9 billion people across more than 180 countries observe Ramadan, one of the five foundational pillars of Islam. Its origins trace to 610 CE, the year Muslims believe the Prophet Muhammad first received the Quran's revelations during this month in the Cave of Hira outside Mecca.

Ramadan doesn't begin on a fixed date. Instead, it begins when a crescent moon is visually confirmed. The Royal Museums Greenwich explains the astronomy behind the sighting, including the conditions that must be met: the sun must be below the horizon, the moon must be above it, and the two must not be within the Danjon Limit (roughly 5 to 7 degrees of separation in the sky, as shown below).
The call to prayer is a distinctive sound marking the start and end of the fast each day, playing a key cultural role in the rhythms of the period. This archive collects "duas" (or supplications, or a prayerful petition) for each day in the year, with timely prayers and recitations sung by the muezzin, or cantor, in gorgeously intricate melodic intervals.
The events following Muhammad's death were a bitter succession dispute that divided Islam into its two major branches. You can relive them in this dramatic narrative from the Conflicted History podcast, which provides an immersive entry point into the issue.
The story behind Ramadan's origins involves a lesser-known layer of personal drama for Muhammad, who fled the Cave of Hira in fear thinking he had been possessed by the angel communicating with him. Only his wife, Khadijah, was able to reassure him. The first revelation came during Ramadan in 610 CE, but the full Quran took 23 years for the angel Jibril (or Gabriel) to deliver.
Because the Islamic year is 11 days shorter than the Gregorian calendar, Ramadan migrates through every season over a 33-year cycle. In 2030, it will fall twice in the same Gregorian year.
The hadith—or record of Muhammad's words or actions—includes an account from Muhammad's third wife, Aisha, who retells the story of Muhammad first receiving the revelation from Jibril. It's one of the most cited primary sources in Islamic tradition, and comes first in the broader Sahih al-Bukhari collection, a compilation of hadiths.
Toward the end of Ramadan, Laylat al-Qadr is observed, recalling Muhammad's "night of power" when the Quran was first revealed, according to Islamic tradition. The Quran describes it as better than a thousand months of worship. Its exact date differs between Sunni and Shia adherents, falling on the 27th night of the month for Sunnis and the 23rd for Shias.
