What This Expression Does
Runs once per day at 6:00 PM server time. Cron uses a 24-hour clock, so 6pm is hour 18 — writing 0 6 * * * would give you 6 in the morning instead.
Use Cases
End-of-workday timing suits jobs that wrap up the day’s activity:
- End-of-day sales, orders, or activity reports
- Backing up files changed during business hours
- Closing out support-ticket queues and sending recap emails
- Powering down or scaling in dev/staging resources overnight
How to Use
- Copy the cron expression above
- Open your crontab with
crontab -e - Add a new line with:
0 18 * * * /path/to/your/script.sh - Save and exit
The 24-Hour Clock Gotcha
The most common mistake with evening cron jobs is writing the 12-hour number: 0 6 * * * (6am) when you meant 0 18 * * * (6pm). Quick reference: add 12 to any PM hour — 1pm is 13, 6pm is 18, 11pm is 23. Midnight is 0, not 24.
