0 CE and 1 BCE are different names for the same year. -1 CE is 2 BCE, -2 CE is 3 BCE and so on. It actually works A fun edge case would be someone using BCE, which runs backwards, *now*, in -2025 BCE

In the US Who Wants To Be A Millionaire? 2nd edition video game from Eidos & Jellyvision, entering your name as "Regis", "Millionaire", or one of the actual $10^6 winners on the show would result in the game changing your name to "Faker" or "Cheater". So I could not play the game as myself.

She is actually 101 and the computer can’t handle an age that high so just put her down as a 1 year old on the manifest. She laughed it off. Legend." / X
