Fluff time: how many days, weeks, etc. into the year is it more than a societal faux pas to have all your Christmas gear in place and working every night?

To put the cookies on the lower shelf, all the lights, inflatables, animatronics, etc. are going full force as it was during the Christmas season, but now it is a new year and they have not been mothballed until Dec. or even left in place but not lit up every night. Maybe people get busy but how far into the New Year can you get a pass for leaving them up? When does it become a bizarre sight and a running joke to not only have your Christmas regalia going at night when Christmas is well passed?
