"The Earth has two major components of motion. First, it spins on its "
"rotational axis; a full spin rotation takes one <firstterm>Day</firstterm> "
"to complete. Second, it orbits around the Sun; a full orbital rotation takes "
"one <firstterm>Year</firstterm> to complete."

"There are normally 365 days in one <emphasis>calendar</emphasis> year, but "
"it turns out that a <emphasis>true</emphasis> year (&ie;, a full orbit of "
"the Earth around the Sun; also called a <firstterm>tropical "
"year</firstterm>) is a little bit longer than 365 days. In other words, in "
"the time it takes the Earth to complete one orbital circuit, it completes "
"365.24219 spin rotations. Don't be too suprised by this; there's no reason "
"to expect the spin and orbital motions of the Earth to be synchronized in "
"any way. However, it does make marking calendar time a bit awkward!"

"What would happen if we simply ignored the extra 0.24219 rotation at the end "
"of the year, and simply defined a calendar year to always be 365.0 days "
"long? The calendar is basically a charting of the Earth's progress around "
"the Sun. If we ignore the extra bit at the end of each year, then with every "
"passing year, the calendar date lags a little more behind the true position "
"of Earth around the Sun. In a few centuries, Winter will begin in September!"

"In fact, it used to be that all years <emphasis>were</emphasis> defined to "
"have 365.0 days, and the calendar <quote>drifted</quote> away from the true "
"seasons as a result. In the year 46 <abbrev>BCE</abbrev>, Julius Caeser "
"established the <firstterm>Julian Calendar</firstterm>, which implemented "
"the world's first <firstterm>leap years</firstterm>: He decreed that every "
"4th year would be 366 days long, so that a year was 365.25 days long, on "
"average. This basically solved the calendar drift problem."

"However, the problem wasn't completely solved by the Julian calendar, "
"because a tropical year isn't 365.25 days long; it's 365.24219 days long! "
"You still have a calendar drift problem, it just takes many centuries to "
"become noticeable. And so, in 1582, Pope Gregory XIII instituted the "
"<firstterm>Gregorian calendar</firstterm>"
", which was largely the same as the Julian Calendar, with one more trick "
"added for leap years: even Century years (those ending with the digits "
"<quote>00</quote>"
") are only leap years if they are divisible by 400. So, the years 1700, "
"1800, and 1900 were not leap years (though they would have been under the "
"Julian Calendar), whereas the year 2000 <emphasis>was</emphasis> a leap "
"year. This change makes the average length of a year 365.2425 days. So, "
"there is still a tiny calendar drift, but it amounts to an error of only 3 "
"days in 10,000 years! The Gregorian calendar is still used as a standard "
"calendar throughout most of the world."

"Fun Trivia: When Pope Gregory instituted the Gregorian Calendar, the Julian "
"Calendar had been followed for over 1500 years, and so the calendar date had "
"already drifted by over a week. Pope Gregory re-synchronized the calendar by "
"simply <emphasis>eliminating</emphasis> 10 days! In 1582, the day after "
"October 4th was October 15th!"
