Guide to Calendar Date Conversion Software
Hermetic Systems publishes several calendar programs which convert (or at least display) dates in fifteen calendars. Sometimes two programs will overlap in the calendars that they support. This page allows you to specify which calendars you are interested in and then to find whether there is one calendar program which converts dates in all those calendars, or perhaps two calendar programs which together do so. Check the boxes below for the calendars (or astronomical items or other features) that you are interested in, then click on the 'Submit' button.
