What is cron expression explainer?
The cron explainer turns a cron string into English and lists upcoming run times using parsers that run in the browser.
How to use it
- Paste a cron expression (5 or 6 fields).
- Read a plain-English explanation.
- See the next scheduled run times. Computed locally.
When to use it
Schedulers fail quietly. Reading “at 09:00 on weekdays” before you ship a crontab avoids a 3 a.m. surprise.
