In the Islamic Calendar app, we have made sure that the user is able to view the current month and year. This is done by showing the day of the week and the number of days in the current month. The user can also change the month and year by sliding the screen. We have also included an option to show the Gregorian calendar.

If the user wants to know what day of the week the Sabbath is, he/she can use the app to find out the day of the week.
