What does */15 0 * * 1-5 actually mean?
Paste a 5-field cron expression and get it in plain English — plus the next handful of times it will actually fire. Ranges, steps, lists and day/month names all supported. It all runs in your browser.
FAQ
Is my cron expression uploaded?+
No. The expression is parsed and the run times computed entirely in your browser — nothing is sent to a server. We count anonymous, aggregate usage on our own server (a page view, that an expression was explained) — never the expression itself.
What cron syntax is supported?+
Standard 5-field crontab: minute hour day-of-month month day-of-week. Each field accepts *, single values, ranges (1-5), steps (*/15, 0-30/10), comma lists, and names — JAN–DEC and SUN–SAT. Sunday is 0, and 7 is also accepted as Sunday.
How are day-of-month and day-of-week combined?+
The standard cron rule: if you restrict both the day-of-month and the day-of-week (neither is *), the schedule fires when either matches. If only one is restricted, both must match. The next-run times shown here follow that rule.
