What is Cron?
Cron is a time-based job scheduler in Unix-like computer operating systems. Users that set up and maintain software environments use cron to schedule jobs (commands or shell scripts) to run periodically at fixed times, dates, or intervals.
A cron schedule is a string comprising five fields separated by spaces:
- Minute: 0-59
- Hour: 0-23
- Day of Month: 1-31
- Month: 1-12
- Day of Week: 0-6 (Sunday is 0)
