Why We Need Leap Years? w/ Neil deGrasse Tyson

追加: 2026-05-06

[00:00:00]Why isn't it possible to construct [music] a calendar that doesn't have leap years? You could do it, but what would happen is it means you care more about the year than you do about the day. You would celebrate the new year at like 3:00 in the afternoon. And then the next year you'd celebrate it at like 12 minutes after 3:00 in the afternoon. And then 20 minutes, it would sort of move through your calendar. So therefore, if you were to do it astrophysically, you would know the exact moment where we returned in our orbit and everybody would celebrate that instant. So then the [music] whole world would celebrate the new year at the same time.
