How to read a cron expression?

A cron expression has 5 fields (minute, hour, day of month, month, day of week). Each field can be a value (5), a range (1-5), a step (*/10) or a list (1,15,30). The asterisk * means "every value".

Examples

• 0 0 * * * — every day at midnight
• */5 * * * * — every 5 minutes
• 0 9 * * 1-5 — 9am Monday to Friday
• 0 0 1 * * — 1st of month at midnight
