Listen, I’m not a Left Brain person. When I look at bank statements, Excel spreadsheets, those huge lighted signs at the airport showing flight numbers and departure and arrival times, my head goes all fuzzy, like it’s filled with cotton balls, my eyes cross, and the numbers seem float up from the surface and scramble. (I wouldn’t call it dyslexia, though, because I got an A in Statistics at Rutgers in 1988. Chuckle, chuckle.)
Anyway, if it weren’t frustrating enough to do things like payroll at work or balancing a checkbook, there’s the whole numbers and time and calendars thing, which Wikipedia attempts to make clear:
The Julian calendar was used in Europe at the beginning of the millennium, and all countries that once used the Julian calendar had adopted the Gregorian calendar by the end of it. So the end date is always calculated according to the Gregorian calendar, but the beginning date is usually according to the Julian calendar (or occasionally the Proleptic Gregorian calendar).
Crystal clear, huh?
As I mentioned in a post a few weeks ago, I’ve been reading all these Best Of lists, not just for 2009, but also lists of what folks consider the Best Of the first decade of the 21st Century.
And as I think about this, my Right Brain orientation doesn’t want to trust my subordinate Left Brain when it screams out that it’s a bit premature to declare an end to the first decade of the 21st Century.
I’m reminded of similar brain hemisphere confusion in the run-up to January 1, 2000. The Y2K Bug hype was in the air and much of the world seemed determined to celebrate the coming of 2000 as the beginning of the Second Millennium. After all, 2000 is such a nice round number, isn’t it? It’s just so Second Millennium-ish!
And yet, if you ask an astrophysicist at NASA, well, it’s not.
Question: I’m 17 years old. I’d like to know when the new millennium starts. Isn’t it Jan 1st, 2001? Why do people get excited about 2000 then? How can I explain this to my friends? Please help.
Answer: You are right that the millennium starts on Jan 1st 2001. There is no year zero, so the first millennium started on January 1, 1 C.E., the day after December 31, 1 B.C.E. The first millennium ended 1000 years later, on the night of Dec 31, 1000/morning of Jan 1, 1001, and the second millennium ends 1000 years after that, on Dec 31 2000/Jan 1 2001.
The main reason people will celebrate the millennium on the night of Dec. 31 1999 is to hold big parties, and to hold them a year sooner than they would otherwise. I expect that, around February, 2000, people will start coming around to the belief that the millennium does indeed start with 2001, and plan their next party accordingly.
By the same highly educated reasoning, this would mean that the first decade of the 21st Century doesn’t end until January 1, 2011.
And so, while I’m happy to have evidence that I can still manage to utilize both sides of my brain, I still intend to party tonight like it’s 2011.
Happy New Year!
Happy Old Decade!
