The phrase “Turn of the century”

Do you use it anymore? If you do what do you mean by it? Used to be used a lot more referring to 19th going to the 20th century. But we are far enough from the 20th to 21st for it to confuse people. I still use it this way but is it time to drop the term and spell out what I mean? If I wanted to talk about the change over 20 years ago I would include the world millennium somewhere in what I’m saying.

What to do with this term…
