Cron Parser

Cron Parser translates cryptic cron expressions (like `0 9 * * 1-5`) into human-readable descriptions and shows the next 10 scheduled execution times.

When to use this tool

• Understanding a cron expression before adding it to crontab
• Debugging why a scheduled job isn't running at the expected time
• Verifying a cron schedule for a CI/CD pipeline
• Learning cron syntax interactively

How it works

Parses the standard 5-field cron format (minute, hour, day-of-month, month, day-of-week) plus optional seconds and year fields. Validates each field against its valid range and computes the next N trigger times by iterating forward through time.
