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).

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.

If there are no geeky topics to discuss, I maintain the MacRumors Members Photo Directory and the free iTunes thread, do my moderator duties, work full time, and do volunteer work.

Luckily, I never eat or sleep and I look like this:

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.

You 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?

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.

This thread is a wee bit old, but with 12/12/12 12:12:12 being today I think it's worth three (better make that twelve) cheers!

I'll be sure to post again when we get to 13/13/13 13:13:13!

What's everyone doing for the big holiday today?

I'm referring, of course, to the 25th anniversary of 8/8/88!

I figured there would be a big countdown in Times Square to 8:08:08am, but apparently not. They must be waiting for 8:08:08pm.

Hope to see you there!

I would rather celebrate the 88th anniversary, since I totally missed the 8th.
