Oh, hello there! AD XLV is the personal website of a human named Vinicius.
Anno Domini 45, before the medieval period, was called the Year of the Consulship of Vinicius and Corvinus. That’s because in the Julian calendar, Romans identified a year by naming it after the two consuls who took office in it.
Apart from the lost etymological connection, there’s little reason to why that became this website’s name, though. I was looking for a domain that was less formal and promotional than a first & last name dot com, aiming to drop the personal brand from the content front. And that made the cut.
(Now you know.)
