It would be very suspicious if our day was such an even number of milliseconds. It isn't, but still pretty cool! Things like this are what leap years are for, after all.
Or does that count? Is that caused by a partial day in the revolution of the earth around the sun or a failure of a day to fit into exactly 24 hours? Or both? Are we talking solar or sidereal days?
- brlewis 8y agoLeap years account for a year not being exactly divisble into days. Leap seconds account for a day not being evenly divisible.
- bwbw223 8y agoHow so? Hours, minutes, seconds, and milliseconds are all man-made units. It’s the failure of 24 hours not fitting exactly into a day, not the inverse. Leap years have nothing to do with milliseconds in a day- it’s days that fail to fit into a year; days and years are defined by the orbit and rotation of the earth. Leap seconds, however, are another story...
- vertexFarm 8y agoI know they are man-made units, but I don't think the men who made the second could measure the length of a day and split it into 86,400,000 units accurately.
