What is the cron format?

Standard cron has 5 fields: minute (0-59), hour (0-23), day of month (1-31), month (1-12), day of week (0-7, where 0 and 7 are Sunday).

The asterisk (*) means 'every' value. For example, * in the hour field means 'every hour'.

Can I use cron for seconds?

Standard cron expressions do not include seconds. The minimum resolution is one minute. Some systems support 6-field expressions with seconds.
