Because the Western calendar is based on an Earth year, its months are divided somewhat arbitrarily, and February is a month with an irregular number of days. By contrast, the Islamic year is 354 or 355 days long based on the moon's cycle, and each month is either 29 or 30 days long.
The Islamic calendar consists of 12 months: Muharram, Safar, Rabi' al-Awwal, Rabi' al-Thani, Jumada al-Ooola, Jumada al-Ukhra, Rajab, Sha'ban, Ramadan, Shawwal, Dhu al-Qa'dah and Dhu al-Hijjah. The months of Jumada al-Oola and Jumada al-Ukhra may also be known as Jumada al-Awwal and Jumada al-Thani, respectively.
