Are advent wreaths a thing outside of Germany?

In the UK we have wreaths of holly that go on the front door, but not as a countdown that ive ever been aware of.

We do have these advent calendars where you open a door every day and there’s usually a little chocolate behind it.

They have become a thing here too.
Not sure if we imported this tradition from you (or the Americans…)
Churches have the wreath with the candles. For some reason the candles have different colours, not sure why.
