FAQ

How to add 0 0 * * * to crontab?

Open your cron jobs with crontab -e and add the following line, then save the file (the job will run every day at 0:00):

0 0 * * * /path/to/script.sh

What time does cron use?

Cron uses the server time. If the job is tied to an exact time, make sure the server timezone is set correctly.

Is there a shorthand for 0 0 * * *?

Yes: @daily. It is the same schedule as 0 0 * * *. The common Linux cron implementations (cronie, Vixie cron) understand it, but not every scheduler does — in cloud services the full five-field form is the safer choice.
