I wish there were more time in a day!

As someone who is always trying to do all the things, I’m perpetually saying “I need more than 24 hours in a day!” Well today, for the first time in 3 years, I’m getting my wish. Today we get a leap second!

Leap seconds, which happen every once in a while, are added to our clocks “to keep Co-ordinated Universal Time (or UTC, the modern replacement for Greenwich mean time), the world standard for regulating clocks, in sync with Mean Solar Time, which marks the passage of time based on the sun’s position in the sky” (Source).

I say “every once in a while” because it’s not on a set schedule, like leap years that occur every 4 years like clockwork (pun intended). When we are going to have a leap second is decided on by the International Earth Rotation and Reference Systems Service (IERS)1.

“Between 1972 and 2012, a leap second has been inserted about every 18 months, on average. However, the spacing is quite irregular and apparently increasing: there were no leap seconds in the seven-year interval between January 1, 1999 and December 31, 2005, but there were nine leap seconds in the eight years 1972–1979.” (Source).

The last time we had a leap second was 3 year ago. Here’s what it looked like:

So enjoy that extra second that you get today, everyone. Try not to spend it all in one place!
