Frequently asked questions

What cron syntax does it accept?

It accepts standard five-field Unix cron: minute, hour, day of month, month and day of week, including lists, ranges, steps and common names such as MON-FRI and JAN-DEC. Some hosted schedulers add a seconds field, so check your platform documentation.

Which timezone are next runs shown in?

Upcoming runs use the timezone configured in your browser. A cron daemon may use a server timezone, so confirm that setting on the host.

Does it send my schedule to a server?

No. The expression and next-run calculation are performed entirely in your browser.
