HOW IT WORKS
A focused tool, with the details that matter.
Explain five-field and six-field Cron expressions and calculate the next five run times. Results include enough context to understand what was calculated, not just a number without explanation.
About this tool
What do the fields mean?
Six-field Cron starts with seconds; five-field Cron starts with minutes. Both end with hour, day of month, month, and day of week.
Which syntax is supported?
Use wildcards, numbers, comma lists, ranges, and steps such as */15 or 1-5.
Which time zone does Cron use?
That depends on the scheduler. Select the same IANA time zone configured by your system.
