Cron explainer
- Asterisk (*) means "any" or "every".
For example, an asterisk in the minute field would mean "every minute". - Comma (,) can be used to specify multiple values.
For example, "1,15" in the minute field would mean "at 1 and 15 minutes past the hour". - Hyphen (-) defines a range.
For example, "1-5" in the hour field would indicate "every hour between 1am and 5am". - Slash (/) specifies increments.
For example, "*/15" in the minute field would indicate "every 15 minutes".
