How are we so precise about time, to the point where we skip skipping a leap year every 400 years, when our reference points are millions of miles away in space?

really precise time is done with really precise clocks 

that use atoms and light for their little tick tocks.

but for leap year extensions, there are easier comprehensions.

to find the way, just count every day.

in four years you're short, so add one more just for sport

but in four hundred years you've gone too far.  the correction, however, is not too bizarre

just leave the calendar alone, and you'll find it hasn't grown.

and so this is the case.  every time has its place.
