FAQ

What cron formats are supported?

  • Default uses standard 5 fields (minute hour day month day-of-week).
  • When 'Use seconds' is checked the tool uses 6 fields (second minute hour day month day-of-week) and the UI will insert or remove the seconds token automatically.
  • Supports lists, ranges, steps, month/weekday names, and the '?' wildcard in day-of-month or day-of-week.

What does custom reference time mean?

  • The starting point used to calculate upcoming runs; by default it is the browser's current time.
  • When enabled you can enter a time in 'YYYY-MM-DD HH:mm:ss' format to be used as the reference.
  • If the input is invalid the tool will show an error and will not compute runs.

How are matching rules handled?

The expression is evaluated in your browser's local timezone. When both day-of-month and day-of-week are restricted, standard cron OR matching rules are used.

Does the tool send my schedule to a server?

No. Parsing and next-run calculation happen locally in your browser.
