Cron Expression Generator

Type or build a cron expression and see exactly what it means in plain English, plus the next times it will run. Supports steps (*/5), ranges (1-5), lists and day/month names — everything standard 5-field cron accepts. Runs entirely in your browser.

Examples

Input

*/5 * * * *

Output

Every 5 minutes

Input

30 9 * * 1-5

Output

At 09:30, Monday through Friday

How it works

The tool reads standard five-field cron: minute, hour, day of month, month, day of week. It checks each field against its allowed range, describes the schedule in plain English and lists the next three run times in your device’s time zone.

Field syntax it understands
Syntax	Meaning
*	Every value
*/5	Every 5th value
1-5	A range
1,15	A list
MON-FRI, JAN	Day and month names
0 or 7	Sunday, in the day-of-week field

When both the day of month and the day of week are restricted, the job runs when either one matches, as standard cron does. Six-field expressions with seconds, shortcuts such as @daily and the Quartz characters ? L W # are not supported and are reported as errors.

Frequently asked questions

What do the five fields of a cron expression mean?

In order: minute (0–59), hour (0–23), day of month (1–31), month (1–12), and day of week (0–7, where both 0 and 7 mean Sunday).

How do I run a cron job every 5 minutes?

Use */5 * * * *. The */5 step in the minute field means "every 5th minute", and the four asterisks mean every hour, day, month and weekday.

Why does my job run on more days than expected?

When both day-of-month and day-of-week are restricted, standard cron runs the job when EITHER matches — not both. This surprises almost everyone.

Are the next run times in my timezone?

Yes, they are computed in your browser using your local timezone. Remember your server may run in a different timezone (often UTC).
