The 21st century started on Januart 1, 2001.

I think that everyone made a mistake because people didn’t start the calendar saying year 1 because that would mean that one year has already passed. They would start at 0. Therefore, a hundred years, including that first year, would bring you to the one hundred year mark or the end of Dec. 31, 100. Two thousand years after the begining of the counting would be Dec. 31, 1999 and the next set would start at Jan. 1, 2000. In other words, a millenium is a thousand years. The end of the first millenium would be the mark between Dec 31, 999 and Jan. 1, 1000. The mark at the end of the second would be between Dec. 31, 1999 and Jan. 1, 2000. 2001 just means that we have completed the first year after the new millenium, not the begining of the new millenium.

Agh wern’t we over this problem already?

It wasn’t really clear. Now maybe I just missed it. I might even be wrong about the whole thing, but I was arguing with my brother over the same issue just recently. If I am wrong, then I have to listen to my brother tell me that I think I know everything.

I quit.

Brandon - I’m sorry for correcting you. Please except my humble apologies.

I’m done… :smiley:

Does that mean that I am right?

Nope. Sorry.

lol
for being a thread about the song of the century it should’ve been called what are the exact dates of the start and end of the century? :stuck_out_tongue:

The United States Government says that the 20th century began January 1, 1901 and ended December 31, 2000, since there is no year zero, it cannot be January 1, 1900 to December 31, 1999.

So all Americans have to deal with that. Im not sure what the Canadian Government thinks though…

Thats all the proof I need :wink:

According to the Hebrew Calendar, this is the year 5765, (I think) which would mean that 5,765 years have passed since they began counting. If this is the year 2003, then that should mean that 2,003 years have passed since they starting counting. The way that all of you are saying, it would mean that the year 2003 is 2,002 years after they began counting. That doesn’t make sense.

No. It makes perfect sense. They started counting with year one, and year one was NOT 1 year after they began counting!

As with most math things, a helpful trick I’ve found is to simplify the problem imensely, so here’s two different ways to do it:

  1. Let’s try to count a decade: starting at year 1, we need to go through ten years, so we get 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 all as part of the same decade. Thus, the second decade starts with year 11. The same logic can be applied to millenia.

  2. Let’s analyze a week (Sunday-Saturday for this example). Numbering the days, we get Sunday=1, Monday=2, Tues=3, etc. Just because Sunday is 1 doesn’t mean that 1 day has been completed already–it means that we are in the middle of the first day. Thus, the start of day 2 marks the completion of 1 whole day. Expanding this to the millenium thing, the start of 2001 thus marks the completion of 2000 years, meaning two whole millenia have passed and we are starting into the third.

A-men to that! :stuck_out_tongue:

I understand what everyone is saying, but they shouldn’t have done it that way.

Now, the question: how does anyone really know that they “started with year one?” It makes logical sense to start with one, not zero, but can anyone really know for sure that they did?

i have seen this before,

instead of 0,1,2,3,4,5,6,7,8,9
its acctually 1,2,3,4,5,6,7,8,9,0(10) just look at the #'s on your keyboard… (Keyboard not number pad :p)

this is an easy way to see why the new century began on Jan 1, 2001

I don’t agree. I think that it makes logical sense that they may have started counting days, not knowing that they would later be counting years. After a few years, they said, “Since the number of days is so large, let’s start counting sets of 365 days, or years, since it takes that long for the Earth to revolve around the sun.” This way, they could have started with year zero, but, at the time, they wouldn’t have called it year zero.

That, of course, implies that the number 0 existed at the time. As far as numbers go, zero is a relatively new addition to Western Mathematics, being introduced sometime in the middle ages despite the fact that both the Babylonians and the Mayans may have developed it earlier. This poses a problem as the Julian calender (on which the modern-day Gregorian is based) existed long before that.

Conclusion: The century went from 1901-2000 (with the new one starting with 2001) and that’s the only way it could have been.

This is not westerm mathematics, it was in Europe. Also, they didn’t need a number zero. They just said, “This is day 365 and soon, the number will be very large. The Earth just completed another pass around the sun so lets count that.” Therefore, that was year zero even though they didn’t call it zero. So, it doesn’t matter whether they had the number zero or not.
