Merriam-Webster has a TIME TRAVELER: https://www.merriam-webster.com/time-traveler/
It displays words and phrases that were first used in print in a particular year. Out of curiosity, I entered my birth year, 1970, and found lots of words and phrases, several of which made me smile: anti-sexist, bad hair day, harissa, love handles, spork, mochi, and generative semantics.
