Cron Tips

A standard cron expression has five fields: minute, hour, day of month, month, day of week — in that order.
*/5 in the minute field means every 5 minutes; */10 in the hour field means every 10 hours.
In classic Vixie cron, if both day of month and day of week are restricted (not *), the job runs when EITHER matches, not both.
Nicknames like @daily, @hourly, and @weekly are shorthand: @daily is equivalent to 0 0 * * *.

Yes, it is completely free with no registration. All parsing and scheduling math happens in your browser.

Yes. Five-field (standard crontab) and six-field (with a leading seconds field, as used by Quartz and Spring) expressions are both supported. Seconds default to 0 when omitted.

Your local browser timezone. Keep in mind that servers usually evaluate cron in their own system timezone (often UTC), so verify the timezone your scheduler uses before relying on the times shown here.

No. This is a read-only explainer: it parses expressions and previews run times. It never executes anything or connects to your servers.

Asterisks (*), steps (*/5, 10-50/5), ranges (1-5), lists (1,15,30), day/month names (MON, JAN), L for last day of month, # for nth weekday, and @daily-style nicknames.
