About the Cron Expression Parser

Cron is a time-based job scheduling system used on Unix-like operating systems. A cron expression is a string of five fields (minute, hour, day of month, month, day of week) that defines when a scheduled job runs. This parser translates any cron expression into plain English so you can immediately understand its schedule.

Common examples: 0 * * * * runs every hour on the hour, 0 9 * * 1-5 runs at 9am on weekdays, and */15 * * * * runs every 15 minutes. Also shows the next five scheduled run times so you can verify the expression fires when you expect.

Frequently asked questions

What are the five cron fields?
Minute (0-59), hour (0-23), day of month (1-31), month (1-12), and day of week (0-6, where 0 is Sunday). An asterisk in any field means 'every'. */5 means 'every 5 units of that field'.
Does it handle 6-field cron with seconds?
Yes — the parser detects whether the expression is 5- or 6-field and adjusts. The 6-field form adds a seconds column at the start and is common in Quartz and some modern schedulers.
