How to Use Cron Expression Parser

What is Cron Expression Parser?

Cron is a time-based job scheduler in Unix-like operating systems. Cron expressions define schedules using five fields: minute, hour, day of month, month, and day of week. Each field supports wildcards (*), ranges (1-5), step values (*/15), and comma-separated lists (1,3,5). Understanding cron syntax is essential for automating backups, reports, and recurring tasks.
