2016 marks the newest Leap Year, and Slooh is celebrating the event with a live show! Join us to learn all about what causes a Leap Year, the difference between the calendar on your wall and the one used by astronomers, and how cultures throughout the world (and throughout history) have marked time for themselves.

Leap Years occur once in every four years, adding a 29th day to the end of February, and were created as a way to keep the Gregorian calendar in sync with the astronomical calendar. Since seasons don’t occur over specific days on their own, they will begin to slip over time, forcing a Leap Day in order to get back on track.

Over the course of human history civilizations have used a number of different calendars to mark and track time. The current popular calendar, the Gregorian Calendar, has only been in use for a little over four centuries, having taken the place of the Julian Calendar in 1582. Before that there were countless others, from the Babylonians to the Maya, and to this day variations exist, including the Chinese and Hebrew calendars, among others. How does the Leap Year affect these systems? Is there a perfect way to quantify our days on Earth? Do other planets experience a similar phenomenon? These are just some of the questions that will be answered in our live broadcast on February 29, 2016.
