= ﻿Time Keeps on Slippin' = The Gregorian Calendar is what most of the world uses. Pope Gregory XIII made this calendar on Feb 25, 1582 it is internationally accepted civil calendar. It is accepted because the Julian calendar was wrong! A leap year is every 4 years the year contains one extra day. The Georgian calendar, February in a leap year has 29 days instead of the usual 28, so the year lasts 366 days instead of the usual 365.

 * 2) What is a leap year? **
 * 3) List three other types of calendars used and how they set up their calendar (ex. Lunar). **

Water Clock- were stone vessels with sloping sides that allowed water to drip at a nearly constant rate from a small hole near the bottom. Other clepsydras were cylindrical or bowl-shaped containers designed to slowly fill with water coming in at a constant rate. Markings on the inside surfaces measured the passage of "hours" as the water level reached them. Sun Clocks- Their moving shadows formed a kind of sundial, allowing people to portion the day into morning and afternoon The mechanical clock was a revolution of timekeeping! Atoms Times zones are regions of earth bounded by lines of latitude. Is zero line of longitude, the zero line of latitude is a given in the form of the equator, but for the longitude line was agreed on an international conference at Washington D.C in 1884 **17) If it’s 10:00 AM in Regina, what time is it in Toronto? London? Moscow? Tokyo? Hawaii?** Toronto 12:00. London 4:00 pm, Moscow 7:00 pm, Tokyo 6:00 am (next day), Hawaii 6:00 am  Daylight Saving Time (or summertime as it is called in many countries) is a way of getting more light out of the day by advancing clocks by one hour during the summer. During Daylight Saving Time, the sun appears to rise one hour later in the morning, when people are usually asleep anyway, and sets one hour later in the evening, seeming to stretch the day longer. No we don't use it in Saskatchewan.  No, there is not a year zero  We are starting a new decade in 2011  Linear time is a concept where by time is seen sequentially, as a series of events that are leading toward something: beginning, and an end. In Newtonian theory it is something absolute in reality, regardless of human perception.  Time repeats it’s self in a cyclical motion In What Steve Miller song does time ‘keep slippin’ into the future’? In the song Fly Like an Eagle!

Dinosaurs were around on this earth for a long time, the oldest human like ancestors awere 4 million years ago, there were four ice ages, and dogs and cats go back 64 MYA! *There are two events that dipity would not let us delete!! But we did do them!*
