Tigrai Calendar is an iPhone application developed by Haile Berhe, offering a user-friendly calendar experience. With easy navigation through a simple swipe left or right to switch between months and years, this app ensures seamless usage. Users can customize their calendar preferences by choosing between Arabic or Geez numerals for days of the month and displaying year numbers in either Geez or Arabic numerals.

Furthermore, Tigrai Calendar provides three different options to display monthly calendar dates, catering to individual preferences. Users can view Tigray Calendar days only, see Tigray Calendar days alongside corresponding Gregorian Calendar days, or display Tigray Calendar days with fully filled Gregorian days. Additionally, the app showcases all holidays for the current year and allows users to view holidays for any other year by swiping right or left.
