Answer 1

more important, who decided that we should work 5 days a week and have 2 days off at the weekend why not the other way around?

Answer 2

Calendars are normally based on astronomical events, and the two most important astronomical objects are the sun and the moon. Their cycles are very important in the construction and understanding of calendars. Our concept of a year is based on the earth's motion around the sun. The time from one fixed point, such as a solstice or equinox, to the next is called a 'tropical year'. Its length is currently 365.242190 days, but it varies. Around 1900 its length was 365.242196 days, and around 2100 it will be 365.242184 days. The Julian calendar was introduced by Julius Caesar in 45 BC. It was in common use until the 1500s, when countries started changing to the Gregorian calendar (section 2.2). However, some countries (for example, Greece and Russia) used it into this century, and the Orthodox church in Russia still uses it, as do some other Orthodox churches. In the Julian calendar, the tropical year is approximated as 365 1/4 days = 365.25 days. This gives an error of 1 day in approximately 128 years. The approximation 365 1/4 is achieved by having 1 leap year every 4 years.

Answer 3

I don't know about the 24 hours (probably the Babylonians or other Arab race), but the 365 days were decided by whoever built the universe.

Answer 4

it takes the earth 365 days or one year to orbit the sun, and it take 24 hours to spin. this is a in a solar calender. yet in a lunar calender it takes on 354 for it to be one year. both of these way to tell time were invented the Mayans and Ancient Egyptians virtually at the same time. lol

Answer 5

whoever decided it...but sumtimes it feels dat a day should hav more or less than 24 hrs but not ezactly 24...nd 365 days in a year is managable...

Answer 6

Is it was based on science and some believes and the people that were here on earth first. That what i think but some how everything work together to make one things diffrent that what it takes for the world to change.

Answer 7

Astrophysics decided.
I year= the length of time for the earth to make one complete orbit around the sun. Currently 365.2+ days.

1 day= the length of time for the earth to make one complete revolution around it's axis.

Answer 8

Chuck Norris

Answer 9

Julius Cesar

Answer 10

I would have to concur: Chuck Norris did it. In fact, days used to last 48 hours, but Chuck Norris got tired of waiting for the next morning, so he round-house-kicked the earth into rotating faster.
