What is a cron expression?

A cron expression is a string of five or six fields representing a schedule — minute, hour, day of month, month, day of week, and optionally year. Cron is used to schedule recurring tasks in Unix systems, CI/CD pipelines, and cloud services. This tool translates cron syntax into plain English and calculates upcoming execution times.
