Well I have family coming on the 25th, leave for Disney on the 28th, am not back until the 4th and have family coming back on the 8th. So my tree remains up the entire time.
Actually I love my Christmas tree and it's collection of family ornaments. We didn't finish putting it up until a week ago. We're set to finish cleaning the house and getting the dining room ready for family on Saturday. The tree is artificial so it can stay up for months without harm. I have the lights connected to the switch on the wall so can flick it on and off as I see fit. It's also in the Living Room which never gets used except at Christmastime.
So I leave it up through the Superbowl.
We also erect a massive train garden every year in the patio room. That does take up space and I have to zealously protect it from the cats. The room is bonechilling cold unless we turn on the gas fireplace so we can just shut it off and not use it.
My garden has been up since Thanksgiving weekend. It's not coming down until Feb/Mar. In fact I have a little Irish beer seller hawking green beer for St. Patrick's Day outside the pub. I got that so I can say my garden can stay up through St. Patrick's Day.
Unfortunately all the blizzards last year made me take the garden down early. Our roof spung a leak right over the town square. Melting ice/snow wreaks havoc.
My exterior lights stay up all year round. (Snowman figure does come inside after winter.) They are plain white icicle lights on the back deck and multicolor lights inside the patio room. I have them on a remote control so I can flick them on as needed and make them party lights.
best part about leaving up the Christmas decorations through winter is enjoying them when the snow falls. I got some gorgeous photos of our train garden with snow just outside.
Mickey didn't look too bad in February either:
Now keep in mind I don't start decorating until Thanksgiving so having my stuff up for a couple months into the new year is nothing. January and February would be pretty dull and sad without these twinkling lights.
