Easy Date Converter is a program to perform arithmetical operations with dates in the Common Era (Gregorian) Calendar and dates in five other solar calendars. It is a bilingual English/German program.

Easy Date Converter provides five calendrical operations:

1. Calculation of the number of days from one date to another.
2. Addition of a number of days to a date and subtraction of a number of days from a date.
2. Addition of a number of months to a date and subtraction of a number of months from a date.
3. Interconversion among Gregorian (a.k.a. Common Era) dates, Julian Calendar dates, ISO 8601 Week dates, Hermetic Leap Week dates, ordinal dates in the form yyyy-ddd and Julian day numbers.
4. Display of a month in any year according to either the Common Era Calendar or the Julian Calendar, with display of the ISO 8601 month corresponding to a given CE month.

Weekend days may be included or excluded in date calculations.

There is an Advanced Version which supports batch processing of date operations.
