Cron Expression Generator — Free Developer Utility

Cron Expression Generator and Explainer — enter any cron expression and instantly get a plain English description plus the next 5 scheduled execution times. Cron is the standard Unix task scheduling system used by Linux servers, cloud services, CI/CD pipelines, and virtually every backend infrastructure. A cron expression has 5 fields: minute, hour, day of month, month, and day of week. The cron syntax is compact but not intuitive — 0 */4 * * * means every 4 hours, but you have to know the field order to read it. Our tool translates any cron job schedule into clear English and shows exactly when it will next run, so you can verify your cron schedule before deploying.

Frequently Asked Questions

A standard cron expression has 5 fields separated by spaces: minute (0-59), hour (0-23), day of month (1-31), month (1-12), day of week (0-7, where 0 and 7 are Sunday). An asterisk * means every value.

The / character means step. */5 in the minute field means every 5 minutes (0, 5, 10, 15...). In the hour field it means every 5 hours. Step syntax works in any field.

Use: 0 0 * * * — minute 0, hour 0, every day, every month, every weekday.

Day of month (field 3) specifies exact days: 15 means the 15th of every month. Day of week (field 5) specifies which weekday: 1 means Monday, 5 means Friday. Using both fields in the same cron expression means either condition can trigger the job.

Some cron implementations support shortcuts: @daily means 0 0 * * *, @weekly means 0 0 * * 0, @monthly means 0 0 1 * *, @yearly means 0 0 1 1 *. Our generator explains these shortcuts too.
