... I know, weird question!

I have a large office where the PM's send out bday cards regularly. I need a formula taking the receivers birthday (example: 31/12/2015, day/month/year) and finding out when I need to send the next card for a 2016 excel workbook. I need to factor in 5 business days for it to arrive on time in the mail.

I've searched this forum in the past and its always been extremely helpful!! Signed myself up today!

Thanks and Happy Holiday Season!
