Run times use your browser’s timezone. Most servers run cron in UTC.
Five numbers and some asterisks decide when a job runs, and misreading them means a nightly task that fires every minute. Paste the expression to see what it actually means and when it will next run.

Frequently asked questions
What order are the five fields in?
Minute, hour, day of month, month, day of week. Hour before minute is the most common mistake — 9 0 * * * runs at nine minutes past midnight, not at nine in the morning.
What does */5 mean?
Every fifth value in that field. In the minute position it means every five minutes. Note that it counts from zero, so it fires at :00, :05, :10 and so on, not five minutes after you deploy it.
What timezone do the run times use?
The times shown are in your browser’s timezone. Most servers run cron in UTC, so if your machine is not on UTC, shift accordingly before trusting the schedule.
