To ask how long a real Christmas tree lasts?

[Qpobb]

Posting here for the poll.

My DP is itching to get our tree this weekend, as we are both feeling a bit down in the dumps and he wants to cheer us both up. However we don't usually get our tree until mid December, and I really want it to last until the first week of January!

For those with real trees, how long has yours lasted in the past?

YABU - Less than 5 weeks.
YANBU - 5 weeks or more.

Thank you

Will it be near a radiator? Ours is and we get two to three weeks max and a ton of needles to hoover.
