Turn of the Century

Reading a recent newspaper about urban redevelopment, I found the writer referring to "Turn of the Century" housing and thought, "That's too recent to need redevelopment".

A few seconds later, it dawned on me: housing from c. 1900! It's dismaying to find myself in a different century to someone else, though I do it all the time too, often referring to things that happened five or six years ago as having been in 1991 or 1992.

I suppose it's just a sign of old age.
