Because originally the holiday just celebrated the first US president, George Washington and then they consolidated into Presidents Day so they didn’t have plethora of Dead President Birthday holidays.
We had Washington’s Birthday and Lincoln’s Birthday both as holidays when I was a kid. Lincoln was born in November, so it wasn’t a perfect balance with February, but it was close enough to one.
