If you follow old traditions, you're all good until 14/15 Feb traditionally for when all Christmas greenery should be taken down. 🎄
Taking down the tree for New Year is very modern and seemingly linked to people putting up trees early in December or even November.
The 12 days of Christmas as a period was created in 567 to bring together Western celebration dates Dec 25 and Eastern dates Jan 6, (some 7th) and in the 9thC, King Alfred, said no work should be done in this period which lead to servants having to work extra hard after to catch up.
Twelfth night Jan 6th for taking tree and greenery down is relatively modern, and seems to be linked to getting servants and laborers to stop celebrating and back to all day working.
19th C It was always Candlemas Feb 2 for it all to be down. But also used to be a really important date. Beginning of the farmers year, and an important date for knowing if you had enough food still for livestock or if you needed to either obtain more or sell animals. Debts needed to be settled and it was also the contract date for many in work or apprenticeship, and traditionally when it started to become possible to work more by daylight.
Most importantly it was the day servants had to have any of the years wages owed to them paid, and could choose to leave or stay.
The church would bless a households candles for free before mass. (rest of the year payment required)
But, the date Feb 2nd for taking down Christmas greenery was moved backwards from Feb 14th/15th by Emperor Justinius 1 to coincide with the 40 day post birth (Epiphany Jan 6th) purification of Mary in the the temple.
Some to this day ignore Justinius 1 decision of moving an ancient 'end of festivities' date to an earlier one for the convenience of the Catholic church, especially if not Catholic, and happily keep to the end of the the first fortnight in Feb.14/15th.
(Many of those start much later too, and 25th of December isn't their Christmas day)
