Leap Day

I learned something about Leap Day/Year today.

I always thought Leap Year was every four years. It's not. It's every four years...

Except for years ending in '00, which ordinarily are not leap years.

Except for years ending in '00 but beginning with a multiple of 4 (16, 20, 24, etc.), which are leap years.

This means that 2000 was a leap year, but 2100 will not be. Which is fine. Except that, unless there are remarkable advancements in the world of medicine in the coming years, 2000 was the only year ending in '00 in my lifetime. I will never witness an '00 year that is not a leap year.

I'm a little disappointed about this. I feel like I missed out.
