# Cron Expression Generator

This cron generator builds a standard 5-field expression (minute, hour, day of month, month, day of week), explains it in plain English, and lists the next five times it will run in your local timezone. You can edit the fields or paste an expression. Invalid input gets a clear message. It runs in your browser.

Runs on your device

## How it works

1. Pick a preset or edit the Minute, Hour, Day of month, Month and Day of week fields.
2. Or paste an existing expression into the Cron expression box.
3. Read the plain English description.
4. Check the next five run times and press Copy.

## Key facts

- **Format**: Standard 5-field cron, with \*, ranges, lists, steps and JAN or MON names
- **Next runs**: Computed in your device's local timezone
- **Day fields**: If both day of month and day of week are set, either can trigger a run
- **Not supported**: Seconds, years and special characters such as ? L W and #

## Common uses

- Schedule a nightly backup and confirm it fires when you expect.
- Decode a cron line found in an old server.
- Double check a weekday-only job before putting it in a pipeline.

## Questions

### What do the five cron fields mean?

In order they are minute (0 to 59), hour (0 to 23), day of month (1 to 31), month (1 to 12) and day of week (0 to 7, where 0 and 7 are Sunday).

### Which timezone are the next runs in?

Your device's local timezone. A server that runs cron in UTC or another zone will fire at different clock times, so check the zone of the system that runs the job.

### Does it accept Quartz or six-field expressions?

No. It expects exactly five fields. Expressions with seconds or Quartz-only symbols get an error that says what is wrong.
