FAQ
What is the field order?
Minute, hour, day of month, month and day of week. Both 0 and 7 mean Sunday.
Why do run times differ from my server?
Cron runs in the server's time zone; pick the same zone here (most servers use UTC).
What if I set both day of month and day of week?
In Linux cron either condition is enough. For example 0 9 13 * 5 runs every Friday and on every 13th.
