Last 2 places I've worked at always had code freezes in December. Only emergency fixes got deployed to production.

Heh, many years ago I worked at a place that deployed Windows 7 to the Windows XP computers only a few days before Christmas. They claimed the migration should transfer all of the emails and files over without an issue.

Goddamn it was a s***show. Broken Outlook accounts (and when that was fixed, missing emails as well), missing files and so on. The helpdesk phone number was constantly giving a busy tone because people couldn't email the helpdesk to open a trouble ticket, because guess what, the email was broken.
