Word of the day: semiquincentennial
Semiquincentennial (also called sestercentennial or quarter millennial) is the 250th anniversary of an event.
I find it really difficult these days to find semiquincentennial birthday cards.
On the other hand, I’m looking forward to the semiquincentennial or 250th anniversary of the 1776 establishment of the United States of America which will fall on 4 July 2026.
