Ratings and Reviews
Months need their number as well as their name
Months are shown with their names but the app should also provide the month's ordinal number within the given year.
Piece of crap
Hebrew calendar does not show the day and year in Hebrew characters. What a joke!! What a rip off. If you need a Hebrew calendar do not buy this one it's a rip off. I want my dollar back. Also I noticed that the actual Hebrew spellings of the months are incorrect. Whoever put this calendar together absolutely does not know what they're doing and does not know the Hebrew language. what a joke
The app really doesn't give the different calculator conversions that you expect, just lays out reference guides and links to Wikipedia on the different calendars while if one selects a certain calendar you get redirected to that calendar app that you must pay for. Don't click on this. Waste of time.
