Parse cron expressions into human-readable descriptions with next scheduled run times.
A cron expression is a string of five fields representing a schedule: minute, hour, day of month, month, and day of week. It's used in Unix/Linux systems, CI/CD pipelines, and cloud services to schedule recurring tasks.
The /5 means "every 5th." So */5 in the minute field means "every 5 minutes." In the hour field, */2 would mean "every 2 hours."
