Islamic Calendar or Hijri calendar is a lunar calendar used by Muslims worldwide to determine the proper day for celebrating Islamic holy days and festivals. The app, developed by Tarek Mansour, is available for iPhone and is free to download.

The Islamic Calendar app features new amazing graphics that support Retina and iPhone 5 screens. It includes a stand clock that displays both the Hijri and Gregorian dates. Additionally, it offers a date converter to easily switch between Hijri and Gregorian calendars. The app also provides the moon phase for any given date.

One useful feature of the Islamic Calendar app is that it displays major Islamic events and festivals on the Gregorian calendar for the current year. It also has an automatic Hijri day adjustment. The app supports both English and Arabic interfaces, based on the language settings of your device. It comes with new colors and improved animations.
