Artist's Description

As if 2016 wasn’t bad enough, it lasts an extra second!

At midnight on 31st December, clocks will read 11:59:60 at midnight GMT/UTC. There will be 86401 seconds in the day, instead of the usual 86400.

This is to keep our time measurement with the spin of the Earth, which has slowed down very very very slightly.

The Earth’s spin can be affected by many things, including large earthquakes and climate patterns. But of course these changes are only very tiny.

Sometimes the Earth’s spin speeds up, and “negative leap seconds” are needed – i.e. a second disappears. How cool is that!

Leap seconds have only been added 26 times since 1972, this will be the 27th.

If we didn’t add leap seconds, the sun would start slipping from the middle of sky at noon.

Leap seconds are decided by the Paris Observatory

Enjoy this very geeky design! For more information check out the Wikipedia article on Leap Seconds:
