    PECALDAYS

    PECALDAYS

    Pecaldays is a powerfull calendar utility for Linux 64bit OSs.

    Pecaldays is a powerfull and portable calendar utility for Linux 64bit OSs. ! It is written in C language. Actually , I made it to support my PEDABA (Data Base) Linux application but , I think it will be usefull as a standalone utility too. You can search for any date you want from 01/01/001 a.C to 31/12/2500 A.C to find the corresponding day. You can also add or subtract number of days to a specific date. It is also possible to extend the Julian calendar (for information only about the corresponding day) beyond 15 October 1582 (official opening of the Gregorian calendar) because, many countries made the transition to the new calendar several years later.
