Hi, I just got a Portofino Perpetual Calendar from my father. He hasn't worn it since 2004, I adjusted over 3000 days to get it up to date. The problem is the date and day of week does not match up. 10/23/2013 should be a Wednesday, but it's showing Tuesday. I'm quite confused, please help. Thank you!
(I'd post a pic, but I don't know how, sorry...)
