==**1.) What is the current calendar most of the world uses / accepts? Explain who made it and why this is accepted. The Gregorian calender is the most used calender in the world. A guy named Pope Gregory created it and the reason its accepted is because it goes through a cycle and it was accepted through Christan churches.** ==

==**2.) What is a leap year? A leap year is a year that contains 366 days,with February 29 as an additional day: occurring in years whose last two digits are evenly divisible by four, except for centenary years not divisible by 400.** ==

==**3) List three other types of calendars used and how they set up their calendar (ex. Lunar).First one is the Muslim calendar it is used in Islamic countries, most of them are in or near Earths torrid zone. Thats where seasonal variation of climate is slight or doesnt exist and the climate is usually hot. The second type is a luni-solar calendar, it is 12 months long, but a 13th month is inserted every few years to keep the calendar in phase with seasons. The third type is the solar calendar, which is based on the length of the year. The calendar we use today is a solar calendar and it evolved from the ancient Roman calendar which passed through the stage of being a luni-solar calendar.** ==

==**9) According to the timeline site how many periods of when are there and list time. There are 21 periods of time on the timeline there is 14000 MYA Big Bang, 4600 MYA Formation Earth, 543 MYA 490 MYA Cambrian, 290 MYA 65 MYA Permian, 245 MYA 65 MYA Mesozic, 5 MYA 2500 BC 4th Millennium BC, 70000 BC Ice Age, 9000 BC 4500 BC First Settelments, 3200 BC 1200 BC 3rd Millennium BC, 1200 BC 332 BC 2nd Millennium BC, 332 BC 63 BC 4th Century BC, 63 BC 476 1st Century BC, 330 1453 Byzantine, 476 1350 Middle Ages, 1350 - 1600 Renaissane, 1500 - 1600 Reformation, 1600 - 1800 Enlightenment, 1750 - 1900 Industrial Age, 1900 - 2000 20th Century, 2000 - 2099 21th Century, 2009 - Future.** ==

==**10) What is an eon, epoch, era, and age? An Eon is an indefinitely long period of time/ age and the largest division of geologic time, comprising two or more eras. An Epoch is a particular period of time marked by distinctive features, events ect... An Era is a point of time from which succeeding years are numbered at the beginning of a system of chronology. An Age is the length of time during which a being or thing has existed.** ==

==**12) List two ancient clocks and how they worked. There is the Sun clocks wich can also be called Sun Dial. The way that the sun clock work is by the way the sun hits the object, then the shadow of the object will move from one side of the object to the other as the sun “moves” from east to west during the day it can been Accurately measured by noon. The second acient clock is the Water clock. The way that this clock works is they were originally made from two containers of water, one higher than the other. The water then travelled from the higher container to the lower container through a connecting tube. The containers had markings on them to show the level of the water and these marks told the time. The design was improved upon over the years and adapted to become easier to use and more accurate. One of the more notable changes was the addition of a floatation device. As the water dripped from the higher container to the lower container, the level of water rose and with it, went the float. This float was connected to a stick with notches that, as it moved higher and higher, moved a hand around a clock face.** ==

==**13) What was a revolution of timekeeping? By the 10th century several types of pocket sundials were used. Then in the first half of the 14th century, large mechanical clock dials began to appear in the towers of several large Italian cities.The invention of spring-powered clocks between 1500 and 1510 by Peter Henlein of Nuremberg. Replacing the heavy drive weights permitted small (and portable) clocks and watches.** ==

==**14) What allows for standard more accurate clocks? In 1721, George Graham improved the pendulum clock's accuracy to 1 second per day by compensating for changes in the pendulum's length due to temperature variations.** ==

==**16) What is the prime meridian? Prime Meridian is base on longitudinal lines. The meridian lines run through Greenwich, England, from which longitude east and west is reckoned.** ==

==**17) If it’s 10:00 AM in Regina, what time is it in Toronto? London? Moscow? Tokyo? Hawaii? If its 10:00am in Regina its 12:00pm in Toronto, in London its 5:00pm, in Moscow its 7:00pm, in Tokyo 2:00 pm and in Hawaii its going to be 11:15am.** ==

==**18) What is Daylight Saving Time? Do we use this in Saskatchewan? Daylight saving is when we move our clocks one hour ahead and "lose" an hour during the night. Each time we move our clocks back one hour we "gain" an extra hour. In Saskatchewan wwe do not use this type of time saving anymore.** ==

==**22) What is cyclical time? Cycilcal time is something that consists of repeating ages, this happened at the every being of the Universe, between birth and extinction.** ==
