QUESTIONS
Frequently asked questions
What do the five fields mean?
From left to right: minute (0-59), hour (0-23), day of the month (1-31), month (1-12) and day of the week (0-6, where 0 is Sunday). * stands for any value, */15 for every 15th, 1-5 for a range and 1,15 for a list.
Which time zone does cron use?
The time zone of the server it runs on, which is often UTC. Run the date command on the server to check. The next runs below can be shown in your local time or in UTC.
Why does my job run twice, or never, on some days?
When both the day of the month and the day of the week are set (not *), classic cron runs the job when either one matches, not only when both do. Daylight saving time changes can also skip or repeat jobs scheduled between 1:00 and 3:00.
