Cron Expression Parser
Explain cron expressions in plain English.
About this tool
A cryptic cron string is easy to misread at 2 a.m. This free cron parser explains schedule expressions so you can verify when a job will fire. Paste a crontab line, read a human summary, and fix off-by-one scheduling mistakes before deploy.
How to use
- Paste your cron expression into the parser.
- Review the human-readable schedule explanation.
- Adjust fields (minute, hour, day, month, weekday) as needed.
- Copy the corrected expression into your scheduler config.
Frequently asked questions
Standard five-field cron (minute hour day-of-month month day-of-week) is the primary target. Some platforms add seconds or special macros.
