Ramadan (Arabic: رمضان Ramaḍān, IPA: [rɑmɑˈdˤɑːn]; Persian: Ramazān; Urdu: Ramzān; Turkish: Ramazan) is the ninth month of the Islamic calendar; Muslims worldwide observe this as a month of fasting. This annual observance is regarded as one of the Five Pillars of Islam. The month lasts 29–30 days based on the visual sightings of the crescent moon, according to numerous biographical accounts compiled in hadiths. The word Ramadan comes from the Arabic root ramida or ar-ramad, which means scorching heat or dryness. Fasting is fardh (obligatory) for adult Muslims, except those who are ill, travelling, pregnant,diabetic or going through menstrual bleeding.
While fasting from dawn until sunset, Muslims refrain from consuming food, drinking liquids, smoking, and engaging in sexual relations; in some interpretations they also refrain from swearing. Food and drink is served daily, before sunrise and after sunset. According to Islam, the thawab (rewards) of fasting are many, but in this month they are believed to be multiplied. Fasting for Muslims during Ramadan typically includes the increased offering of salat (prayers) and recitation of the Quran. From https://en.wikipedia.org/wiki/Ramadan.
