The Islamic calendar (it is known also as Muslim calendar or Hijri calendar) is a lunar calendar based on 12 lunar months in a year of 354 or 355 days. It is use to date events in many Muslim countries (together with the Gregorian calendar), and used by Muslims as a guidance to celebrate their holy days and festivals.
Islamic Date
Its first year was year during which the Hijra, i.e. the emigration of the Islamic prophet Muhammad from Mecca to Medina, occurred. Each numbered year is designated either H or AH. Thus, A limited number of years before Hijra (BH) are used to date events related to Islam, such as the birth of Muhammad in 53 BH.

The starting time for a new date in Islamic calendar is different with Gregorian calendar where Gregorian calendar change its date at midnight. The Islamic calendar change its date at sunset. Each lunar month begins at the time of the monthly “conjunction”, when the Moon is located on a straight line between Earth and the Sun. The month is defined as the average duration of a rotation of the Moon around the Earth (29.53 days). By convention, months of 30 days and 29 days succeed each other, adding up over two successive months to 59 full days.
Islamic Months
The Islamic calendar, however, is based on different set of conventions. Each month has either 29 or 30 days, but usually in no discernible order. Traditionally, the first day of each month is the day of the first sighting of the hilal shortly after sunset. If the hilal is not observed immediately after the 29th day of a month then the day that begins at that sunset is the 30th. That is the reason why a number of days within one month are different for some countries. And it is difficult to make the calendar based on formula because of that behavior.
