Cron expression generator

Pick how often a job should run and get the cron expression for it, explained in plain English with the next run times.

Good to know

What are the five fields?
Minute, hour, day of the month, month and day of the week, in that order. * means every value, */5 means every fifth, and 1-5 is a range, like Monday to Friday.
Which time zone does cron use?
Your server's, which is often UTC. Check before scheduling something for a particular local time.
Know when a job doesn't run
Add a heartbeat monitor: your job pings a URL when it finishes, and Spot Downtime alerts you if the ping is late.

Get told the moment it breaks

Checking by hand only tells you about right now. Spot Downtime checks your sites around the clock and alerts you by email, Slack or Discord.
