What is a Cron Expression?
Cron is a time-based job scheduler found in Unix-like systems. A cron expression uses 5 fields — minute, hour, day of month, month, and day of week — to define when a task should run. Special characters like * (every), , (list), - (range), and / (step) let you create complex schedules.
Field Reference
Minute (0–59) · Hour (0–23) · Day of Month (1–31) · Month (1–12) · Day of Week (0–6, Sunday=0). Use * for "every", */5 for "every 5th", 1,15 for "1st and 15th", and 1-5 for ranges.
