What's the last posting day for cards to the UK?

Anyone know the last day for posting cards to the uk, as usual i have left it to the last minute

Just a thought but I wouldn't trust any last posting days they list. Allow for at least two or three more days before that date just in case. In fact you're probably better off getting your Christmas cards sent off as soon as possible. :)

EDIT: Google is your friend. Apparently the UK Royal Mail's last posting date to Spain is 13 December so I would assume the same applies in the other direction using Correos more or less.
