The cron facility of Unix allows periodic tasks to be started. You need to add a scheduler entry to cron (via crontab) in the form:
minute hour dom month day-of-week
So the entry:
0,15 3-5 * 12 0 /run/some/script
would run the file /run/som/script on the hour and 15 minutes past the hour, from 3 - 5 a.m. every day of the month for December if the day is a Sunday.
