🔒 Everything runs 100% in your browser. Your files and input are never uploaded to any server.
Click to select the minute, hour, day, month, and weekday, and this tool instantly generates a standard 5-field cron expression along with a human-readable, plain-English description. You can express exactly the schedule you want without memorizing crontab or CI scheduler syntax.
How to use
- Start from a 'common examples' button, or configure each field yourself.
- For minute and hour, choose every minute / every N / a specific value; for day, choose daily / a specific day.
- Press the month and weekday buttons to turn on only the values you want (leave them off for all).
- Check the finished cron expression, then copy and paste it into your scheduler.
FAQ
- Are my inputs sent to a server?
- No. Generating the expression and computing the description all happen entirely inside your browser, and no data is ever sent to or stored on a server.
- Where can I use the generated expression?
- You can use it as-is in most schedulers that support the standard 5 fields (minute hour day month weekday), including Linux crontab, GitHub Actions, Jenkins, and more.
- What happens if I specify both day and weekday?
- In standard cron, specifying both day and weekday means it runs on any day where either one matches (an OR condition). The generator's plain-English description also shows this as 'on day ~ or ~ weekday'.
