How many seconds a day have?

Pretty neat example of how you shouldn’t calculate days/weeks from Swizec Teller. If you think that day is equal 60 * 60 *24 seconds - this post’s for you. Thanks to the wonder that is daylight savings time (DST), we have a day that’s only 23 hours long. We also have a day that’s 25 hours long. Then, every few years, we have a day that’s 86,401 seconds long. In theory, we could even have a day that’s 86,399 seconds long....
