1401 is a free and customizable calendar for iOS devices that has a built-in Qibla compass to help you find the direction to Mecca, so you can celebrate the occasions that are important to you.

You can choose between the default Calendar app and this one, which lets you customize the weekdays, as well as the number of days in a month and a year. This is useful if you want to celebrate a specific day in the Islamic calendar, or if you need to find the right day to start or end your fasting.

To use this application, first, set your location to your city or town, and then select your country.
