datemath is a command line date and time math utility.
This program performs various operations on mm/dd/yy, mm/yy, and YYMM dates, and it sends the results to the standard output. This function will most often be used in shell scripts surrounded by “ characters.
The expressions accepted by datemath are straightforward and moderately flexible. The grammer is defined to reject most things that don’t make any sense (such as adding two dates together), while allowing most things that do.
This is free and open source software.
