Good to know
- This is what the shortcut @weekly means. Note that it is the night from Saturday to Sunday, not from Sunday to Monday.
- Weekly jobs run only 4 or 5 times a month, so a single silent failure costs a whole week. Get an alert when one does not run.
Typical uses: Weekly backups, cleaning up old data, weekly digests.
