When was the US Constitution last amended?
7 May 1992
The 27th Amendment, on congressional pay
It was proposed in 1789 as part of the original package that became the Bill of Rights, and took 202 years and 224 days to ratify — by a wide margin the longest gap between proposal and ratification in American history. It was revived in 1982 by a University of Texas undergraduate, Gregory Watson, who wrote a paper arguing it was still live, received a C, and then spent a decade lobbying state legislatures until it passed.

This page gives a date and never a "years ago". These pages are built as static files, so a computed interval would freeze at build time and quietly become wrong — which on a reference site is worse than making the reader do the subtraction.
