Automation

I have the following requirement, please can you confirm if this can be done.

I have setup a field in my contacts called 'Occupation Date' which is a date somewhere in the future of the contact been setup.  

Say for example, the Occupation Date is set for 1 November 2013, how can i automate the system so that it sends off an email template automatically when this date is reached?

Thanks
Richard
