Ready-to-use Crontab config
Drop this into your project. The expression is the one above.
30 8 * * 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
- Day-of-week is 0-7 with both 0 and 7 meaning Sunday. Names (MON-FRI) are accepted by most implementations.
- Fields are minute, hour, day-of-month, month, day-of-week. There is no seconds field, so one minute is the finest resolution.
- 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 minute comes first, then the hour. 30 8 means 08:30, while 8 30 would be an invalid hour.
