Cron HelperCron expression for every day at 9 AM
At 09:00, every day.
Five fields for Linux, GitHub Actions and Kubernetes (minute hour day month weekday). Six or seven for Quartz. Nothing you type leaves your device.
What it means and when to use it
Hours use the 24-hour clock, so 9 is 9 in the morning and 21 is 9 in the evening. A fixed morning time is the usual answer for anything a person reads with their tea: a daily email, a reminder message, a status report. To change the time, change only the two numbers: 30 7 * * * is 07:30 and 45 18 * * * is 18:45 (minute first, hour second).
Watch out for this
The most common surprise is the time zone. If the server is in UTC and you want 9:00 in India (UTC plus 5 hours 30 minutes), the server time is 03:30, so you write 30 3 * * *. Do the sum before you save the line, or set the zone for the job. The tool above can show the next runs in your zone and in UTC at the same time so you can check the answer.
What each field says
| Field | Written | Means |
|---|---|---|
| Minute | 0 | 0 |
| Hour | 9 | 9 |

An example of the next runs
If it were Friday 13 November 2026 at 10:20 UTC, the next six runs would be these. Times are shown in UTC and in India time (UTC+5:30).
| UTC | India time |
|---|---|
| Sat 14 Nov, 09:00 | Sat 14 Nov, 14:30 |
| Sun 15 Nov, 09:00 | Sun 15 Nov, 14:30 |

The same schedule in other places
Quartz
Quartz has a seconds field in front, uses ? in one day field, and counts Sunday as 1:
0 0 9 * * ?GitHub Actions
Scheduled workflows run in UTC unless you add a time zone. In the workflow file:
on:
schedule:
- cron: '0 9 * * *'Kubernetes CronJob
In a CronJob manifest the schedule goes in spec.schedule. Without spec.timeZone, it is read in the time zone of the cluster's controller:
spec:
schedule: "0 9 * * *"
timeZone: "Etc/UTC"A crontab line to copy
The command is made up. Replace it with your own and use full paths:
0 9 * * * /home/me/bin/morning-email.sh >> /home/me/morning.log 2>&1Questions
How do I run at 9 AM India time on a UTC server?
India Standard Time is 5 hours 30 minutes ahead of UTC, so 9:00 IST is 03:30 UTC: write 30 3 * * *.
Can cron use AM and PM?
No. Cron only takes numbers from 0 to 23 in the hour field.
