What's the Cron expression format?

Standard Cron has 5 fields: minute hour day month weekday. Some systems support 6 fields (with seconds).

Asterisk * matches all values for that field. * * * * * means every minute.

How to specify weekdays?

Use 1-5 in the weekday field for Monday-Friday. Both 0 and 7 represent Sunday.
