The Islamic and Gregorian calendar is a type of time counting for the year, encompassing various categories of days, weeks, and months. The Islamic calendar consists of 12 months, with 4 of them being sacred, following the lunar calendar. Each month begins the day after the sighting of the crescent moon, and if the moon is not visible, an extra day is added. The Gregorian calendar, named after Jesus, consists of 12 months based on the solar cycle of 365 days.
