Welcome to the forum.
Very similar problems have been solved umpteen times in these fora. Did you use the search function, or have a look into the links at the bottom left under "More UNIX and Linux Forum Topics You Might Find Helpful"?
Date / time arithmetics is one of the worst tasks in IT, as many subtleties have to be covered / taken care of. It's not just checking we have two two-digit numbers separated by a dash. Certain months allow for certain days only. Do you need leap year dates considered?
You can use numerical comparisons, or string matching, for validations. What be your favorite?

service
service(8) System Manager's Manual service(8)
NAME
service - run a System V init script
SYNOPSIS
service SCRIPT COMMAND [OPTIONS]
service --status-all
service --help | -h | --version
DESCRIPTION
service runs a System V init script in as predictable an environment as possible, removing most environment variables and with the current
working directory set to /.
The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT. The supported values of COMMAND depend on the
invoked script. service passes COMMAND and OPTIONS to the init script unmodified. All scripts should support at least the start and stop
commands. As a special case, if COMMAND is --full-restart, the script is run twice, first with the stop command, then with the start com-
mand.
service --status-all runs all init scripts, in alphabetical order, with the status command.
EXIT CODES
service calls the init script and returns the status returned by it.
FILES
/etc/init.d
The directory containing System V init scripts.
ENVIRONMENT
LANG, TERM
The only environment variables passed to the init scripts.
SEE ALSO
/etc/init.d/skeleton,
update-rc.d(8),
init(8),
invoke-rc.d(8).
