About: Here you can check the Julian and Gregorian calendars side-by-side.

The program can show years from 1 AD to 9999 AD. Before 1582 AD the Gregorian calendar does not exist; British territories have adopted it in 1752; all countries -- before World War Two.

Enter the desired year in the textbox above and push the button "OK". You can also click on the links for previous - next years.

In order to get the correct dates, it is essential to open the exact year and not another one, because the difference between the two calendars vary between the centuries. Check the reference links for more information.

This software is created in the hope that it would be usefull but without any warranty for fitness for a particular usage. If in doubt, please use a pencil to verify the results.
