Frequently asked questions

Which cron syntax is supported?

The standard 5-field syntax used by Linux crontab: minute, hour, day of month, month and day of week, with *, lists, ranges, steps, names like MON and JAN, and shortcuts like @daily.

What if I set both a day of month and a day of week?

Like Linux cron, the job runs when either one matches. For example 0 0 13 * 5 runs on the 13th and on every Friday.

Which time zone are the next runs in?

Your device's time zone. A server runs cron in its own time zone, which may differ.
