reet,
If they are really closed down, you don't have to worry about it too much - since they would get/open mails of 3rd and 4th Jan on 6th and it would/should really not matter to them if your mail was delivered on 3rd or 4th. The expiration date for the offer they would have mentioned depending on what date they were sending the letter to you.
Secondly, even if they are working on 3rd and didn't receive your check by the end of business of 3rd, they are not going to offer your place on the same day - and if at all they would do - they would do only on 4th.
Thirdly, mostly everyone would understand your situation and cannot give you such a big punishment for such a minor mistake. Not only that nobody would like to lose a better student.
Suggestions:
First you can leave voice-mail and drop e-mail to them - just in case they are working on weekends and not picking up phones etc. due to their workload.
Secondly you can call up FedEx and ask them to expedite the service so that they deliver it on 3rd itself.
Hope this helps!!
