Seriously, how long is the Christmas season? Seriously?

I was told that it used to last until the Feast of the Presentation? or Purification? or Candlemas? but that it no longer does.
"Officially."
I mean, old babushkas might still leave their Precious Moments angels out, but the post VCII Church knows better.
Epiphany's come, rip down all that garland and put the lights away for the year.
Right?
So what gives in Rome?

From Dec. 19 to Feb. 2,[emphasis mine] Paul VI Hall will also be adorned with a tree and a Nativity scene designed by Mexican artists.

Just so you know, my tree's staying up till February.
