Chris Wilson notices a mathematical-calendrical quirk: if March 5th is 35, then 35×35 = 1225 means that March 5th squared is December 25th, so March 5th is the square root of Christmas! Pair this with Pi Day (3/14), and you get a nerd celebration:

I hereby declare that:

- March 5th shall be known as the Square Root of Christmas and
- The 10-day interval between the Square Root of Christmas and Pi Day shall be known as Nerdigras

Let the festivities begin!

Bob Congdon10:21 PM on 4 Mar 2009Ancient joke: why do programmers confuse Christmas and Halloween?

Because DEC 25 == OCT 31

Giacomo7:20 AM on 5 Mar 2009I'm afraid Europeans and other ISO-following countries won't be able to join you in the festivities...

Eduardo7:50 AM on 5 Mar 2009Also: 3/3/09 was Square Root day.

Michael Tobis10:36 AM on 5 Mar 2009I am calling 9/9/09 Negativity Day ('nein, nein, nein') but that's still a ways off.

Michael Tobis10:38 AM on 5 Mar 2009Euro Pi Day is surely 22/7 . Celebrate with python and pie.

Robert K10:44 AM on 5 Mar 2009I like the idea, Ned, but if you really want this to catch on we're gonna need some traditions and cheesy songs.

On the first day of Nerdigras, my imaginary girlfriend gave to me a hash map in a B-Tree.

On the second day of Nerdigras my imaginary girlfriend gave to me two Turtle functions and a hash map in a B-Tree.

On the third day of Nerdigras my imaginary girlfriend gave to me, three unmatched parens, two Turtle functions, and a hash map in a B-Tree.

On the fourth day of Nerdigras my imaginary girlfriend gave to me, four calling stacks, three unmatched parens, two Turtle functions, and a hash map in a B-Tree.

... okay, a little help here? 'Cause apparently I suck at this!

Ned Batchelder12:14 PM on 5 Mar 2009@Robert, I think you gave us a good start!

On the fifth day of Nerdigras, my imaginary girlfriend gave to me, five golden ratios! Four calling stacks, three unmatched parens, two turtle functions, and a hash map in a B-tree.andrew12:39 PM on 5 Mar 2009When is the Airing of Grievances?

Bob Congdon1:34 PM on 5 Mar 2009@Ned, how about:

On the sixth day of Nerdigras, my imaginary girlfriend gave to me, six trees sp-laying, five golden ratios! four calling stacks, three unmatched parens, two turtle functions, and a hash map in a B-tree.Rob Hudson1:39 PM on 5 Mar 2009For these 10 days, we no longer say YES, we say AFFIRMATIVE. (Flight of the Conchords allusion)

Jonathon Duerig4:30 PM on 5 Mar 2009I'll add a couple of verses:

On the seventh day of Nerdigras, my girlfriend gave to me, seven pointers dangling, six trees sp-laying, five golden ratios! four calling stacks, three unmatched parens, two turtle functions, and a hash map in a B-tree.

On the eighth day of Nerdigras, my girlfriend gave to me, a byte, seven pointers dangling, six trees sp-laying, five golden ratios! four calling stacks, three unmatched parens, two turtle functions, and a hash map in a B-tree.

Alex Kesling5:08 PM on 5 Mar 2009On the ninth day of Nerdigras, my imaginary girlfriend gave to me, a printout of Graham's Number, one corrupted byte, seven pointers dangling, six trees sp-laying, five golden ratios! four calling stacks, three unmatched parens, two turtle functions, and a hash map in a B-tree.

Steve M.5:34 PM on 5 Mar 2009Also heard that yesterday was Brass Band Day--"March Forth," nyuk nyuk.

Tony Williams7:02 PM on 5 Mar 2009Hey guys, haven't you written poetry before - it needs to scan better.

On the eighth day of nerdigras my nerd love gave to me eight bits a zeroed, seven pointers dangling, six trees a splaying, five golden threads, four calling stacks, three base tens, two turtle funcs and a hash map in a balanced search tree.

nickf7:31 PM on 5 Mar 2009@Rob: yes, affirmative!

Alex Kesling9:04 PM on 5 Mar 2009I vote we leave the last lyric open for improv.

Kelly Yancey10:50 PM on 5 Mar 2009I vote we stop at 010.

Jonathon Duerig12:49 AM on 6 Mar 2009@Tony: I thought it would be a deliberately awkward pause to emphasize the 'a byte' thing. But we can use your version instead if you want.

@Kelly: But there are 012 days in Nerdigras based on the original post. So I suppose that we should just count up to 012 since it looks more similar to the original.

So the full song would go like this:

Robert K7:08 AM on 6 Mar 2009Since I started this, maybe I can wrap it up with one last (ha!) iteration.

On the twelth day of nerdigras I sent my ISP...

(all together now!)❧ 12 fracking fractals

❧ 11 puns so stunning

❧ 10 bits a twiddling

❧ 7 pointers dangling

❧ 6 trees a splaying

❧ Fiiiive RFID rings

❧ 4 calling stacks

❧ 3 unmatched parens

❧ 2 Power Gloves

❧ ... and a hash map in a B-treeeee!

kbob5:36 PM on 6 Mar 2009Here's another one from the 1970s: PDP-11 day, celebrated twice a year, both on DEC 11 and OCT 13.
