Run a Cron Job Every Day at 11 AM
To run a job every day at 11:00 AM, use 0 11 * * *. The 0 is the minute, 11 is the hour on a 24-hour clock, and the three stars mean every day of the month, every month, every weekday.
The expression
0 11 * * * fires at 11:00 every day. Minute = 0, hour = 11 (24-hour time, so 11 AM), and the rest are wildcards.
Change the minute
For 11:30 AM use 30 11 * * *. The first field is minutes 0–59.
Timezone note
Cron uses the server's local timezone. Check it with timedatectl. If the job fires an hour off, the server clock or TZ is the usual cause.
FAQ
What is the cron expression for every day at 11 AM?
0 11 * * * runs daily at 11:00 AM. The 11 is the hour in 24-hour time and 0 is the minute.
How do I run a job at 11:30 AM instead?
Use 30 11 * * *. The first field sets the minute, so 30 means half past eleven.
Why does my 11 AM cron run at the wrong time?
Cron uses the server timezone. Run timedatectl to check it; a wrong TZ or clock shifts every job.
