The Western calendar is a mishmash of bodges and compromises. The day we call 1 January is a human invention, and wasn't in fact the start of the new year until the Gregorian calendar was adopted, in the 16th century over much of Europe but not until 1753 in England.
New Year celebrations are about the symbolism and magic of numbers, not about reality. Does Dr Williams watch in fascination as the car mileometer clicks over to 10001? The 2001 exponents are mathematically right, but have missed the point.
