Yes that was a Bank Holiday I did have

Hi just wanted to find out how this works. I handed in my notice on 19/12/2012 and my last day is 18/01/2013. My normal entitlement to annual leave is statutory minimum of 28 days (including all bank holidays). I think proportionally therefore I should have 1 day worth of annual leave to use for the calendar year 2013 but I have been told that I will be paid for this unused leave instead. Therefore am I being paid for the 13 working days I am doing this year (2 Jan to 18 Jan) or am I being paid for 14? As surely normally speaking I should be paid for 13 days even though I am taking one off for annual leave?
