How many Feb. 29s have you seen?

As a glorified bump to this thread which appears to be stalled out at the moment I have built this table of Julian Days for the Feb/29 of the years shown, using Julian Date Converter (which has a good description of what that entails), and a resulting span of ages for that particular year’s Leap Day.

All of them.

Just to see if there’s any way to pull together the data from past threads that have dealt with ages and years when Dopers were born and such details, I have backtracked through the threads I’m familiar with to build this list:

===============================

If you know of other threads dealing with these topics, I’d appreciate a link to them.

I was a fetus in Feb '76, so I didn’t count that one. 9, from 1980 onwards.

Good answer! I suspect fewer than 1 in 10,000 fetuses (feti?) remember such stuff anyway.
