Excel copied its date processing from Lotus 1-2-3, which was the dominant spreadsheet in the '90s. Excel also copied - deliberately - a bug in Lotus 1-2-3 which assumed 1900 was a leap year.

Lotus 1-2-3 copied a lot of features from SuperCalc (I don't remember whether SuperCalc automatically formatted dates), and SuperCalc copied a lot of features from VisiCalc, which was the first spreadsheet.

A lot of features which you might associate with MicroSoft Office go back to the '80s or earlier.
