crontab once per week and once per month?

I put a crontab line in to run once every Sunday.
Is this correct * * * * 7 command?
Or will that run it every minute of the day on Sundays only?
Should it be 00 00 * * 7 ?

How can I run something once per month?

The first will run every minute on Sundays. Usually we represent Sunday with 0 instead of 7, but I think most (if not all) distributions can handle either 0 or 7. The second entry will run at midnight Sundays.

To run monthly, you can use @monthly (will run at midnight on the first of the month), or you can specify a day of month and time to run on a more specific schedule. References/examples below.

You can use :

00 00 * * 0
This will run at midnight of Sundays.

And for running something once per, let's say 1st day of the month then you can use:

00 00 1 * *

This above entry will run your code 1st day of every month at midnight.
