1900 wasn't a leap year. Lotus 1-2-3 got it wrong first. It had to fit in 640k. Excel copied the bug on purpose. So sheets could move between them.

Thanks Chris. For those who haven’t seen it, there’s a great write up about the creation of VBA, by the Microsoft program manager Joel Sposky.
In that article, Joel talks through that 1-2-3 to #Excel date handling idiosyncrasy, and the super stressful face-to-face spec review of VBA he had with Bill Gates.
