Where can I find a Christmas Countdown clock?

I'm looking for a Christmas Countdown clock. But I don't want one of the ones where you copy and paste the code. I want and acurate Christmas Countdown of Days, hours, minutes, and seconds. I want to be able to copy the COUNTDOWN (not a code) and so wherever I paste it, the countdown will keep working. I looked everywhere, but I couldn't find one. All the good ones had code. Eastern Time Please.
