Geocache Description:


What will you do with your extra day in 2012?

Join us at Milly's Tavern in Manchester, NH on February 29, 2012 for a 29-minute geo-celebration of leap year. The event will run from 6:30 PM until 6:59 PM. Be sure to arrive on time so you don't miss out on this quadrennial event.


The event will be held in the function room at Millie's Tavern. This room has its own outside entrance that management would prefer we use to minimize traffic in the main bar and dining room. The entrance is located next to the parking lot on the side of the building. I will post a geocaching sign on the door. Thanks and looking forward to seeing everyone!

History of Leap Year

A year is not exactly 365 days; it actually takes the planet 365.242 days to complete a revolution around the sun. After four years, those extra .242 days add up to a whole extra day.

Even then it’s not exactly perfect because .242 times four is not 1. We get around this problem by skipping a leap year for three out of four century years. So the year 2000 was a leap year, but the years 2100, 2200 and 2300 will not be

Like many advancements in civilization, the concept of a leap year came from the Egyptians. The Egyptians first began using a calendar with a leap year during the Ptolemaic dynasty (300-30 B.C.E.) Many people credit Julius Caesar for the use of the leap year in his Julian calendar, but he almost certainly took the ideas from the Egyptians. One legend says that he took the idea from his lover Cleopatra.

When Caesar returned to Rome and implemented the calendar the leap year became popularized. It would remain unchanged until the 16th century A.D.

In 1582 Pope Gregory XIII introduced a new, but very similar, calendar. As we mentioned earlier, you actually add slightly too much time to the year by adding a day every four years. This results in an unnecessary extra day being added to the calendar once every 128 years. This annoyed Gregory. He believed that this extra day ever century and a quarter had resulted in Christian holidays being celebrated on the wrong days.

So Gregory went ahead and did something about it by inventing the Gregorian calendar, which we still use today. The Gregorian calendar introduced the concept of skipping three of four century years as a leap year, and so keeps the balance a bit better than the Julian calendar.

So there you are. Now that you know the science and history behind your extra day, what are you going to do on it?
