A simple logical interview question

A simple logical interview question was asked to Rahul by the interviewee:
There is exactly one week between Christmas and New Year. Thus a New Year that occurs right after the Christmas, happens to occur on the same day as Christmas. But in 2015, Christmas will occur on Friday and New Year will occur on Thursday.

How is that possible?

Rahul was able to answer the question. Can you?
