Why use cron expression examples?

Even experienced developers second-guess cron syntax. Is 0 3 * * 1 Monday at 3 AM or January at 3 AM? Starting from a verified example eliminates guesswork. Each example below shows the expression, a plain-English description, and the next several run times so you can confirm it does what you expect.

Common scheduling patterns

The most requested cron schedules are: every minute (*/1 * * * *), every hour on the hour (0 * * * *), daily at midnight (0 0 * * *), every weekday at 9 AM (0 9 * * 1-5), weekly on Sunday (0 0 * * 0), first of every month (0 0 1 * *), and quarterly (0 0 1 1,4,7,10 *). These cover the vast majority of automation use cases.

Frequently Asked Questions

What cron expression runs every day at midnight?

The expression 0 0 * * * runs at 00:00 (midnight) every day. The first 0 is the minute, the second 0 is the hour, and the three asterisks mean every day, every month, every day of the week.

How do I run a cron job on weekdays only?

Use 1-5 in the day-of-week field. For example, 0 9 * * 1-5 runs at 9 AM Monday through Friday. Day 1 is Monday and day 5 is Friday in most cron implementations.
