jackpot

Today is 05/05/05.

I've been enjoying that stuff ever since the turn of the century. For the first few years I was constantly doing little calculations. If you know how to view page source, you can see a bunch of them, but I won't bore my regular readers.



I've got an email to my prof half-written. That has nothing whatever to do with the multidude of little math calculations hidden in the html. Nothing, I assure you.

After all that typing I wanted to put that stuff somewhere... so here it is in the comments.

How many dates each century have consecutive numbers? There must be twelve, one every year from '03 to '12 (01/02/03 and 12/13/14 being the first and last). Or eleven if you're European & can't get above 11/12/13.


But what if you count both digits? Then 01/23/45 is the only one.

And what if you count all four year digits--how many consecutive dates will there be by the year 10,000? Just one: 01/23/4567

You can also have fun considering how many dates in each century are like today--slot machine jackpot days. From 01/01/01 to 12/12/12 there will only be twelve days total and we've already had five of them!

What if you were less strict about zeroes and slashes, to include days like 2/22/22?

This is more complex.

1/1, 1/11, 11/11, in the years '01 and '11 (subtotal six)...
2/2 and 2/22 in the years '02 and 22 (subtotal ten)...
The rest of the months one day each (3/3 etc), two years each ('03 and '33)...
So ten days, each twice a century, is twenty days, plus our subtotal ten...
Thirty days total.

But if you went to the year 10,000 and only allowed "pure" years--such as the years 2, 22, 222, and 2222--that would be 36 pure years.

Most of those years would only have one matching day (3/3/3333). But the 1's years have two extra days (36 + 8 = 44) and the 2's years have one extra day (44+4=48).

Wow... 48 total... could I have figured that out more easily?

You're either a math geek or have OCD. ;-)

Both.

No, not really. But the whole point of OCD is of course to ease anxiety by doing little routines, so in a sense I was using a similar technique to fill a similar need.

And I'm definitely a math geek, although not many people know this. ;)
