Ready-to-use Crontab config
Drop this into your project. The expression is the one above.
*/15 9-17 * * 1-5 /path/to/command >> /var/log/job.log 2>&1The Crontab fields, in order: minute (0-59), hour (0-23), day-of-month (1-31), month (1-12), day-of-week (0-7, 0 and 7 = Sunday).
Things to watch out for in Crontab
- A step such as */15 restarts at the top of each unit, so it only gives even gaps when the step divides 60 (minutes) or 24 (hours).
- Day-of-week is 0-7 with both 0 and 7 meaning Sunday. Names (MON-FRI) are accepted by most implementations.
- Cron runs in the server's local time zone. Check it with the date command, or put CRON_TZ=Asia/Kolkata above the line on cronie-based systems.
The common mistake with this schedule
The last run is 17:45, not 17:00, because the hour range is 9-17 and the minute step still fires inside hour 17.
