It's $year-1900, not 1900-$year.

And it's a fix for an old custom that started a long time ago (70s - 80s) when they thought "2-digit years should be enough for any date".

So when 2000 came along, they had a problem. Replacing 2 digit years with years since 1900 was the easiest, backward compatible fix.
