What is a cron expression?
Cron expressions schedule tasks with five or six fields: minute, hour, day, month, and weekday, with an optional year. They are common in Linux, CI/CD pipelines, and serverless jobs.
When to use this parser
- Checking whether a cron schedule means what you think it means
- Finding the next run times for debugging
- Learning fields such as
*/15, ranges, and lists
The parser gives human-readable descriptions and next run times, so you can validate a schedule before deploying it.
