Easy Date Converter is a program to perform arithmetical operations with Gregorian, Julian and Annus Novus dates and Julian day numbers. (It is a trilingual English/German/Spanish program.)

Suppose a meeting is scheduled for exactly ten weeks (70 days) from Christmas Day 2003. What date will that be? (Don't forget that February 2004 has 29 days.) If you find this sort of calculation a tad difficult this program will make it easy.

Easy Date Converter provides three calendrical operations:

1. Calculation of the number of days between two dates.
2. Addition or subtraction of a number of days to or from a date.
3. Interconversion among Gregorian (a.k.a. Common Era) dates, Julian Calendar dates, dates in the Annus Novus Calendar, Julian day numbers and dates in the form yyyyddd (sometimes erroneously called "Julian dates")
