Ramadan is the ninth month of the Hijrah calendar, which is also known as the Islamic or lunar calendar. The Hijrah calendar is based on the cycles of the moon, and it consists of 12 months. Ramadan is a significant month for Muslims because it is the month during which fasting, or Sawm, is observed. Fasting is one of the Five Pillars of Islam and involves refraining from eating, drinking, and other specific activities from dawn until sunset each day throughout the month.
