At what time date turns in Islamic calender?

In the Islamic calendar, a new day begins at sunset, specifically at the time of the Maghrib prayer. This means that the date changes from one day to the next when the sun sets, rather than at midnight as in the Gregorian calendar. The Islamic calendar is lunar, consisting of 12 months, which are either 29 or 30 days long, resulting in a year that is about 10 to 12 days shorter than the solar year.
