Does apple review apps during the holiday break?

Solution 1:

iTunes connect is shut down for the holidays. Just because there are new posting on appreviewtimes.com doesn't necessarily mean the apps were just reviewed. Could be from the weekend.

Solution 2:

This is what apple wrote in the mail do developers:

As a reminder, from Monday, December 22, through Monday, December 29, 2014, iTunes Connect, Application Loader, and iTunes Connect for iOS won’t be available.

During this time, you won’t be able to submit new apps, app updates, or In-App Purchases. You also won’t be able to access iTunes Connect or make changes to TestFlight Beta Testing
