What we are demonstrating:
Here we have an eclectic mixture of holidays and events from many different calendar systems. (Not a complete list, by any means!) The purpose of this little program is to show how we can effortlessly translate any such mixture of dates and events from one system, the system you designate with the “FROM” popup to any other (designated by the "Convert" Popup.)

In a business scenario, suppose you managed a corporation that had offices in Tel Aviv, Beijing, Riyadh and Auckland. All offices are on different calendar systems, what do their special dates mean to you? We solve that with ease. "); For an added twist, we can display the conversion information in any calendar system you want (under the "Convert" column). So, you might want to designate your conversion from the context of the Japanese Era Calendar, but have the results displayed in the context of the Bahai calendar (while we translate the native dates from their native calendars to you). This is all mathematical translation, not table lookup. We don’t go via the Gregorian calendar first, nor do we require it.

Also, we draw your attention to the additional astronomical event we have: First Sunday After the First Full Moon After the Spring Equinox. We like astronomy, too.
