Yes it's lit 24 hours a day
Im pretty sure the tree in Portland's living room is the day before or after Thanksgiving and it stays lit until New Years day or a few days after (24/7)
https://www.travelportland.com/events/holidays/ This is not much. But I will report more when I find it. No Peacock Lane this year. It looks like Zoo Lights is on. ;) I saw the tree being driven onto Pioneer Square this year. And it is up. Lights are next to be put on!
