Happy 1 2 3 4 to math/calendar geeks!

[Doctor Q]

In American representation, today's date (December 3, 2004) is 12/3/4. It's not often that we get four consecutive digits in the date, so we should enjoy it while it lasts. Maybe we should eat pi for dinner, or spend $1234 at the Apple Store, or something else suitable to the occasion.

In the 21st century, we'll have the following four-consecutive-digit days to celebrate:

01/2/3 (last year)
1/23/4 (earlier this year)
12/3/4 (today)
3/2/10
4/3/21
5/4/32
1/2/34 (same digits as today)
6/5/43
2/3/45
7/6/54
3/4/56
8/7/65
4/5/67
9/8/76
5/6/78
6/7/89
3/21/0 (see note)

Did I miss including any?

Note: I consider 3/21/0 in the 21st century to be March 21, 2100, based on the assumption that the 1st century was the year 1 through the year 100. If you prefer to think of centuries as starting on years ending in 00, then you should put that date first in the list (March 21, 2000).

kinda nifty...

for european date system (day/mo/year)...

01/2/3 would be feb. 1, 2003
1/23/4 would be jan. 23, 2004
12/3/4 would be march 12, 2004
23/4/5 would be april 23, 2005
2/3/45 would be march 2, 2045
3/4/56
4/5/67
5/6/78
6/7/89
7/8/90

japanese system (year/mo/day):

01/2/3 would be feb. 3, 2001
12/3/4 would be march 4, 2012
23/4/5 would be april 5, 2023
34/5/6 ...
45/6/7 ...
56/7/8 ...
67/8/9 ...

that's it, i think? :confused:

Unless I'm blind, you forgot 1/23/45 and 12/3/45.

[Doctor Q]

Unless I'm blind, you forgot 1/23/45 and 12/3/45.I was talking about Four-Consecutive-Digit Day but Five-Consecutive-Digit Day is even more exciting!

Doc. Q, what else do you do with your time? First the gigapixel photo, now finding all of those dates...

And what about the '0's? Today is 12/3/04 or 12/03/04 depending on how you write it out.

Thanks Doc.....

I remember going to a square root day in engineering school, Sept 9th 1981.

Revel in your compulsive disorder and may we all benefit!

I think that you do your job well. We are very lucky here at MacRumors. Your vast knowledge is appreciated. I'm wasn't at all surprised by your post, something that's routine for a math genius. In my personal case it's a math phobia. :D

[Doctor Q]

I'm wasn't at all surprised by your post, something that's routine for a math genius. In my personal case it's a math phobia. :DYou can balance your checkbook, right? You can tell which size container is the best deal at the supermarket, right? That's just practical everyday math. So maybe you aren't math phobic and shouldn't sell yourself short. Maybe it's just not your hobby or area of interest. Only a small percentage of people are math fanatics or totally math-averse. The rest are in the middle, using math when it's useful, being amused at patterns other people point out (like today's date), and OK with or without it otherwise.

I'm not a genius, just someone who likes math, pattern matching, and puzzles.

Which reminds me. When the Google founders first talked about their public offering, they estimated the share value as $2,718,281,828. Math geeks will realize that they were both predicting how much they could raise and making a math joke. Who wants to reveal what it was?

If I go to L.A. then I'll keep an eye out for you...

Thanks for your threads and your wasted time! :p

Don't worry the evil math geeks will be taken care of...

NEW YORK - A public school teacher was arrested today at John F. Kennedy International Airport as he attempted to board a flight while in possession of a ruler, a protractor, a set square, a slide rule, and a calculator.

At a morning press conference, Attorney General John Ashcroft said he believes the man is a member of the notorious Al-gebra movement. He did not identify the man, who has been charged by the FBI with carrying weapons of math instruction.

"Al Gebra is a fearsome cult," Ashcroft said. "They desire average solutions by means and extremes, and sometimes go off on tangents in a search of absolute value. They use secret code names like 'x' and 'y' and refer to themselves as 'unknowns', but we have determined they belong to a common denominator of the axis of medieval with coordinates in every country. As the Greek philanderer Isosceles used to say, 'There are 3 sides to every triangle'."

When asked to comment on the arrest, President Bush said, "If God had wanted us to have better weapons of math instruction, He would have given us more fingers and toes." White House aides told reporters they could not recall a more intelligent or profound statement by the president.

Hrm, striking resemblance to Euler's number. All I know is that it's the only number that when raised to the power of x, remains the same through integration and differentiation.
