The title bar it too dark and definitely did not scream Christmas to me; it wasn't until I noticed the colored numbers that I realized what it was. I'd suggest dropping the title and just going with the numbers.
If it's really necessary to do something for Christmas why not just a small tree next to the logo, or perhaps replacing it. Changing the color scheme to me doesn't really add much Christmas flair to anything, it just makes the familiar design more jarring.
