Cron uses 5 space-separated 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). * means 'every', */n means 'every n units', and ranges like 9-17 specify an inclusive range.

What does @daily mean?

@daily is shorthand for '0 0 * * *' — runs at midnight every day. Other aliases: @hourly (0 * * * *), @weekly (0 0 * * 0), @monthly (0 0 1 * *), @yearly (0 0 1 1 *).

What is the difference between 0-7 and 1-7 for day of week?

Both 0 and 7 represent Sunday in most cron implementations. Day 1 is Monday through day 6 is Saturday.

How do I run a job every 15 minutes?

Use */15 * * * * — the */n syntax means 'every n units'. For every 15 minutes: */15 in the minute field. For every 2 hours: * */2 * * *.
