Notification setup - 1st day of each month

Hi! Does anybody know how to setup a notification to be sent to a user on the 1st day of each month?

As i want to customise the notification I setup a workflow with 1 state only for this.

Basically on the 1st day of each month the workflow is triggered and sends a link to a view to a user.

Any ideas?

Many Thanks,

Nuno
