There is the second day of Christmas in many European countries, at least in the Netherlands were I grew up and Germany where I spent many winter vacations. On the other hand we never celebrated Christmas Eve. Christmas is first and second Christmas day: 25th and 26th of december. (This is as far as my knowledge goes. Christmas has always seemed an extremely religious holiday to me growing up and we didn't celebrate it in any way. Presents came from Sinterklaas the 5th of december so the whole gift-giving aspect for secularists is absent.)
