Frequently asked questions
What does this CRON explainer do?
Paste any CRON expression and it returns a plain English description of the schedule plus the next 10 times it will run, so you can confirm a job fires when you expect.
Does it support 5-field and 6-field CRON?
Yes. It handles the standard 5-field format (minute, hour, day of month, month, day of week) and the 6-field format that adds a leading seconds field.
What do the special characters like * and */15 mean?
An asterisk * means every value for that field, a slash sets a step (so */15 in the minute field means every 15 minutes), and ranges like 1-5 in the day-of-week field mean Monday through Friday.
Example: what does 0 9 * * 1-5 mean?
It runs at 09:00 every weekday — minute 0, hour 9, any day of the month, any month, on days 1 through 5 (Monday to Friday).
