How to use / FAQ
Which cron syntax is supported?
Standard five-field cron with *, ranges (1-5), lists (1,3,5), and steps (*/15). Month and weekday names (JAN, MON) work too, as do the @hourly, @daily, @weekly, @monthly, and @yearly macros.
How are day-of-month and day-of-week combined?
Following the standard cron rule: if you restrict both fields, a job runs when either one matches. If only one is restricted, that one applies.
What time zone are the run times in?
The schedule is evaluated in UTC, and each upcoming run is shown in UTC alongside your local time for reference. To convert a specific run time to or from an epoch value, use the Unix timestamp converter.
Does it support seconds or @reboot?
No. It reads the classic five-field format plus the @hourly–@yearly macros. Six-field expressions (with a leading seconds field) and @reboot, which some schedulers add, aren't part of standard cron.
