Frequently asked questions
What does each cron field mean?
A 5-field cron expression is: minute, hour, day of month, month, day of week.
What do * and */5 mean?
* means every value. */5 means every 5th value, for example every 5 minutes in the minute field.
What happens if both day of month and day of week are set?
Standard cron runs the job when either matches. The explanation says so when both are set.
Does it support seconds or special strings like @daily?
Not yet. It supports the standard 5-field format used by Linux crontab and most schedulers.
Which time zone are the next runs in?
Your local time by default; tick the box to see them in UTC. Your server's time zone decides when the job really runs.
