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.
