    You can count as you wish. The rest of the world counts differently, but being individualistic is great. And I'm especially thankful that arguing about which year a decade starts or ends is the most important thing we have to worry about. I hope the next decade doesn't bring any worse worries! ;P

    From Wikipedia:

    The 2000s is the decade that started on January 1, 2000 and will end on December 31, 2009. It is the current decade, and the decade in which the 21st century and 3rd millennium began.

    From dictionary.com:

    a period of ten years beginning with a year whose last digit is zero: the decade of the 1980s.

    There is only one way which is correct. When you say, "the rest of the world," you're not referring to that same group of people who think the world will end in 2012, are you? Or maybe you're referring to that large group of people who never finished high school, or maybe.....

      No, decade rules follow century rules. New centuries started in 1800, 1900, etc, therefore a new decade begins with 0 not 1. (This is true in binary also as the basic beginning point is 0.) So, the new decade began in 2000 and then will again in 2010, with the 1 and 0 being the determining factor. For example, the new decade began in 1980 and again in 1990 because of the 8 and the 9, i.e. the 80's and 90's. So, in conclusion 2010 starts the beginning of a new decade just as 2020 will in the future. :)

      You have constructed a direct proof. The logic is correct, however your initial assumption that centuries start with xx00 is incorrect. Therefore your result is not proven. Centuries start with xx01. There was no Year 0. Years are 1-based. At some point in history we had a zero event, after which we started the first year (Year 1 AD, or Year 1 CE, your choice, unless you're Muslim, Jewish or anyone else who uses a different Zero Event). At the END of that year, we started Year 2. Eventually we get to Year 10 at the END of which we've completed 10 years. The NEXT decade starts at Year 11. The 1st century (1 - 100) The 2nd century (101 - 200) ... The 20th century (1901 - 2000) The 21st century (2001 - 2100) In other words, we're using Z+, the set of positive integers. It's no wonder that so many people have problems with this. It took mankind centuries to come to grips with the concept of 0. In fact, it wasn't until fairly recent in human history that 0 was accepted as a number at all. Maybe it will help if you use the clock. In English 2:30 AM is 2:30 AM. In German I could say that the time was halb drei == half of three. Why? because 12:00 AM to 12:59 AM is the FIRST hour. The END of the first hour/start of the second hour is 1:00 AM, etc.

          You're arguing against the dictionary definition at this point, do you care to take another swing or can we just accept that it makes a lot more sense to start counting from 0 rather than claiming the 90s went from 91-2000?

            Look, open your mind instead of just defending your position: Here's a bunch of years: 1,2,3,4,5,6,7,8,9,10 11,12,13,14,15,16,17,18,19,20 21,22,23,24,25,26,27,28,29,30 You'll notice that there are TEN years in each group. That means each group is a decade. Now what year begins the second decade that I have listed above? Notice that at the beginning of my "calendar" is year 1 because the calendar we use today began at year 1.

              No, but you immediately started the FIRST year of your life. At the END of which you celebrated your 1st birthday. In other words, you completed your FIRST year on your FIRST birthday. If you are in finance, you would call this 'using end mode'.

                12am to 12:59am is the FIRST hour of the day but it is not 1. It is before 1. Same with the beginning of time.

                  You're confusing the literal beginning with the calendar's beginning. The calendar began with year 1, not zero.

                    Since so many otherwise intelligent people made snarky remarks about my assertion that the decade begins in 2011, not 2010, I will explain it quite simply as follows: Premise: There are TEN years in a decade Year 1 is the FIRST year of the decade Year 2 is the SECOND year of the decade Year 3 is the THIRD year of the decade . . . Year 9 is the NINTH year of the decade and here's the important part: Year 10 is the TENTH year of the decade, meaning that the new decade doesn't begin until Year 11. That means that 2010 is the TENTH year of the FIRST decade of the 2000's. The second decade will not begin until 2011. Arthur C. Clarke knew the truth, and that is why he named his book 2001 A Space Odyssey, not 2000 A Space Odyssey

                        The world is full of people who believe incorrect things. When he says that mathematics is subject to individualism, he's wrong. When he implies that just because lots of people believe the wrong thing, that that makes it true, he's wrong again.

                          No, you are not 1 year old, but you are living in your FIRST year. The time you take your first breath is the first second of your year 1, not the first second of your year ZERO. It’s exactly the same with the decades: 1970 is in the 70’s because in the first day of 1970 the seconds of the next 1971 are ticking.

                            Simply, because the calendar never started with the year 0. People didn't walk around saying March 1, 0. The calendar started with year 1. So that's why decades, and centuries, and millenia all begin with 1.

                                But the first year is the first year, i.e. Year 1, NOT year 0. Let's say you have a child who was born 1 Jan 2001. On 1 Jan 2010, they will celebrate their 9th birthday. On that day they will begin their 10th year of life, not their 9th, Even though they are only 9 years old. At the END of 2010 they will have COMPLETED their 10th year. Year 1 = 2001 Year 2 = 2002 ... Year 9 = 2009 Year 10 = 2010. http://en.wikipedia.org/wiki/Year_zero[^]

                                    Hmm. The year before that, (or even one or two years before March 1, 1), they weren't saying March 1, -1 either. Does that prove anything? :|

                                      Maybe it requires having argued about 0 and 1 based indexes for too long in college to get a kick out of this.

                                        Simply, because the calendar never started with the year 0. People didn't walk around saying March 1, 0. The calendar started with year 1. So that's why decades, and centuries, and millenia all begin with 1.

                                        People didn't walk around saying March 1, 1 either, they thought it was 753AUC or something like that

                                          I certainly don't. I just like arguing. I don't have anything better to do today. ;P
