How Did Ancient Romans Invent Roman Numerals?
In 46 BCE, Julius Caesar made a single year last 445 days just to fix a calendar that had drifted three months out of sync with the seasons — and the fix he landed on is still running your phone's calendar today. In this video we trace the actual mechanics of the Julian calendar: the corrupt priestly system that broke Roman timekeeping in the first place, the Egyptian astronomer who redesigned it from scratch, why September through December are still named after the wrong numbers, and the emperors who tried to rename entire months after themselves — including one whose full twelve-month vanity calendar would have put Christmas in a month called "All-Surpassing Conqueror." We also look at the tiny 11-minute flaw Rome's fix never caught, and the correction to the correction that's still causing calendar mismatches in historical records today.
