How do I parse a cron expression?

Enter your cron expression in the input field (5 fields: minute, hour, day, month, weekday). The plain-English description appears instantly, along with the next 5 scheduled execution times and a field-by-field breakdown.

What cron syntax is supported?

The parser supports standard 5-field cron syntax including wildcards (*), step values (*/5), ranges (1-5), and comma-separated lists (1,3,5). The 6-field variant with seconds is not supported.
