What This Expression Does
Runs once per day at 9:00 AM server time — minute 0, hour 9, every day of every month regardless of weekday.
Use Cases
9am is the canonical start-of-business hour, so this slot fills up with:
- Daily standup reminders and task-list notifications
- Publishing scheduled content as the audience comes online
- Opening-bell data pulls (prices, rates, availability)
- Escalating overnight alerts that nobody acknowledged
How to Use
- Copy the cron expression above
- Open your crontab with
crontab -e - Add a new line with:
0 9 * * * /path/to/your/script.sh - Save and exit
Weekends Included — Is That What You Want?
0 9 * * * fires on Saturday and Sunday too. For business-hours jobs that’s often noise (or worse, a 9am Sunday push notification). Restrict to weekdays with 0 9 * * 1-5. And as always, 9 means 9am in the server’s timezone — set CRON_TZ= if your audience lives elsewhere.
