This!

Man's been woken up on New Years Day.
Wife: Oy, wake up, it's 12 o'clock!
Man: No details. What Decade Is It?

2000 to 2009 - how about "the units"?

Dana, imagine you're a 9 year old kid. From the moment you were born until your first birthday they referred to your age as months. You had not reached a year yet. After a full year had passed, they referred to you as 1 year old.

If you are a 9 year old kid, and your 10th birthday is approaching. On your birthday, you have reached the end of your first decade because at this point you have lived 10 full years.

0 to 1
1 to 2
2 to 3
3 to 4
4 to 5
5 to 6
6 to 7
7 to 8
8 to 9
9 to 10


10 = 10 years have passed = 1 decade.

100 = 100 years have passed = 1 century

1000 = 1000 years have passed = 1 millennium

2000 = 2000 years have passed = 2 millennium

This means 1900 was the last year of the 19th century. 1901 was the first year of the 20th century.

2000 was the last year of the 2nd millennium and 2001 was the first year of the 21st century.

If:
Then 1899 to 1900 was the last year of the 19th century. It ended, technically, on Dec. 31, 1899.

Not:

I think the quality of this thread has decade

Oh, are you keeping score?

it's more of a half-score -a rimshot perhaps

This
and this


contradict each other.

No they don't. If you are nine, and about to turn ten, you are in year ten. If the calendar had started when you were born, the first year would be year one, and at the end you would be one year old. You would be ten years old at the end of year ten.

Sure, I get what you are saying, but I didn't think Radar said that.

Sorry I cannot process your trains of thought but this thread reminds me of the last Sunday morning show.

The news person said that no pet name for this last decade was made because no one wants to own it and now I know why. People can't even decide how to count the days in a year.

Well duh, one at a time. :rolleyes:

I think he did. Your tenth birthday is the end of your tenth year, and the end of the 1900th year is the end of the 19th century.

Your tenth birthday is the end of your 9th year. You begin a 10th year.

A human lifespan isn't counted in the same way as the earths.
It has leap years and leap seconds.




18th century

1701-1800


19th century
1801-1900


The Twentieth Century of the Common Era began on January 1, 1901 and ended on December 31, 2000. according to the Gregorian calendar, (2000 was the first century leap year since 1600).

In the Gregorian calendar, a Century leap year is a year that is exactly divisible by 400 (and, thus, as with every other leap year, qualifies for the intercalation of February 29). The years 1600 and 2000, for example, were century leap years; the century years of 1700, 1800, and 1900 were not century leap years. The next century leap year will occur in 2400. Century leap years always start on a Saturday, and the February 29 intercalation of such years is always a Tuesday.
The century year "divisible by 400" rule of the Gregorian calendar was considered an improvement over the previously utilized Julian calendar which had provided for a leap year every four years; this practice resulted, over the centuries, in too many leap days being added to the calendar and placing it out of step with the astronomical seasons.
