Merge Field to Show Day of The Week Relating to Date Field?

Merge Field to Show Day of The Week Relating to Date Field?

Hi I am creating a custom template for sales orders.

Using the ${SalesOrders.Due Date} merge field I can show the date associated with our Due Date custom field but I want to also show the day of the week that goes with this date when the sales order is printed.

Does any know how I could do this?

many thanks in advance.
