Accepted job offer on Friday - No response

I may just be over worrying but I received an official job offer on Friday (December 20th). The offer letter stated that I must accept within 24 hours. I responded and accepted immediately. In my acceptance email, I asked a few follow up questions. I haven't received a response yet.

​

I know today is Christmas and New Years is coming around the corner. My start date (per the letter is January 7th). When should I follow up again? I don't want to annoy people but I really want to make sure I have the job.

​

Thanks!
