Paste a 5-field cron expression to get a plain-English explanation. Covers common patterns — exotic expressions may not be fully described.
About this tool
Translates a 5-field cron expression into a plain-English description of when it runs, plus a field-by-field breakdown — useful for double-checking a schedule before deploying it, since cron syntax is easy to get subtly wrong.
Frequently asked questions
What do the 5 fields in a cron expression mean?
In order: minute, hour, day of month, month, and day of week. A common source of confusion is that both "day of month" and "day of week" exist as separate fields — when both are restricted (not *), most cron implementations treat it as an OR, not an AND.
Does this tool support 6-field cron expressions with seconds?
Not currently — it expects the standard 5-field format. Some schedulers (like Spring's or Quartz's) use a 6th leading seconds field, which would need to be removed before pasting here.
