Good idea, but I can see some room for improvement

The main problem for me, so far, is that this is a stand alone calendar app which doesn’t seem to synch with my system’s calendar (which I was hoping for) and is very poor, except for symbols, at identifying which calendar we are looking at. It does, however, do a fine job of showing me how others around the world are measuring today. I’m looking forward to improvements with the app, and what they may be.

I also find a problem with trying to keep the Hebrew calendar on top. I keep getting a duplicate of the Gregorian calendar that, when I attempt to remove it, gets rid of the Hebrew calendar, and eventually is now removing the Buddhist calendar. If I try narrowing the window to a few that I want to keep on top then the Hebrew calendar automagically closes and that duplicate Gregorian tab replaces it. This is a problem which I leave to the programmer, but, for now I cannot recommend this to my Jewish Friends.

Only converts today’s date

This program only converts today’s date. I wanted a program that coverts past dates into different calendars. So for my purpose this program doesn’t work.
