# Run on every second Tuesday of the month
20 4 8-14 * * test $(date +%u) -eq 2 && /usr/bin/bash /home/user/mytuesdayscript.sh
Run at 04:20 on every day-of-month from 8 through 14.
- 20 = 20th minute
- 4 = 4am
- 8-14 = between day 8 and day 14 (second week)
- * = every month
- * = every day of the week
But we are testing if day is number 2 (Tuesday. Sunday is 0) and we only run the script in this day.
