[edit] Pi Approximation Day

...get a life


Are you sure about this?
Back home, we always celebrate Pi Approximation Day on April 26th. This is the day on which the planet Earth completes approximately 2 Astronomical units' worth of its annual orbit, in other words orbit / part travelled = pi.

-)

A better Pi day would be 31 April.ping 09:09, 23 Oct 2003 (UTC)

I've added the first one to the article, what about April 31st, why that date? --Ævar Arnfjörð Bjarmason 01:36, 2004 Jul 23 (UTC)
There is no 31 April. Angela. 18:58, Jul 23, 2004 (UTC)
In many places, the standard format for writing dates is day/month/yeay, not moneth/day/year. In the d/m/y format, April 31st is 31/4, while March 14th is 14/3. Angela's observation is there is no 31st April is, of course, mere pedantry :-) Oh, and happy Pi Day! 82.33.127.78 08:49, 14 Mar 2005 (UTC)

[edit] This can't be right

"the day on which planet Earth completes two Astronomical units' worth of its annual orbit: on this day the total length of Earth's orbit, divided by the length already traveled, equals π (that is, the Earth has travelled one radian in its orbit)."

Shouldn't that be two radians (two AU = two radians)?

Yes. I have changed this.
Now, would anyone care to figure out when Ultimate Pi Day would be in the (say) Islamic calendar?  :-) —Dah31 01:22, 12 October 2005 (UTC)
It should be two radians, but if that got changed, it must have been reverted. I don't really see what's special about two radians compared to, say, one radian. I changed the date[1] to reflect that, since then I could also remove the blurb about leap years, simplifying things a bit. Any thoughts? —HorsePunchKid→龜 2007-03-14 21:30:39Z

[edit] Pi Day

I've also seen 22 July as Pi Day (22/7). I'm not sure how common this is, so I've refrained from putting it in the article for now. --Zundark, 2002 Jan 4

Polish TeX group (GUST) is also celebrating Pi Day. Should we add it? szopen

Sure, go ahead and add it! Also I've made a link to Pi Approximation Day which was referred to above. --Chuck Smith

should the UK pi day be 31st April? ;-) -- Tarquin

Should the article be titled "Pi Day" or "Pi day"?

I'd say Pi Day, like May Day, Labor Day, Arbor Day, Christmas Day, yadda yadda. --Brion

Tarquin: since 1 AU = earth's orbital radius, 1 radian = 1 au. in this case the two terms are interchangable, you can use radians or AU. However, since the earth's orbit is eliptical instead of round, it would probably be safer to use AU. - Tim

[edit] Deletion?

  • Pi Approximation Day This is made up. A joke. It does not belong in an encyclopaedia. MrJones 18:06, 19 Oct 2003 (UTC)
    • I've never heard of that one, but there is Pi Day, which is March 14 (3/14). That's kind of a joke too, but it's a "real joke" I suppose. Adam Bishop 18:18, 19 Oct 2003 (UTC)
      • That page also should die. MrJones 19:24, 19 Oct 2003 (UTC)
        • Why? In any case, at least we don't have an article about the Prime Number Shitting Bear :) (Yet...) Adam Bishop 19:38, 19 Oct 2003 (UTC)
          • It is rubbish and doesn't tell one anything. Why keep it? I don't deny it exists, but should we have informaton about every 'day' that gets invented? Every site that refers to it that I found was either cranky or otherwise full of nonsense. It doesn't really bear consideration. Throw it out. MrJones 20:07, 19 Oct 2003 (UTC)
            • Actually, at my high school (albeit a math and science HS) we did celebrate Pi day. And I've heard several other references to it since then. It's a legit phenomenon --Raul654 20:47, 19 Oct 2003 (UTC)
            • Just because it's strange doesn't mean it should be deleted. Evil saltine 00:27, 20 Oct 2003 (UTC)
            • We had Pi Day at my high school too (although I don't really recall anything special happening, except the math and science teachers being excited...) Adam Bishop 00:44, 20 Oct 2003 (UTC)
    • Delete. I would say that Pi Day is quite enough, thank you. -- BCorr ¤ Брайен 00:52, 21 Oct 2003 (UTC)
    • Keep. Wartortle 21:36, 22 Oct 2003 (UTC)
    • Move content to pi and redirect. -- Minesweeper 01:32, Oct 21, 2003 (UTC)
    • Pi Day is definitely real. PAD I'd never heard of, but it seems to get plenty of Google hits. Yes, I think we should keep information on 'days' if they're really observed (by a non-negligible number of people). The information could as well be folded into pi, as long as it's kept, but I don't see the need. -- VV 07:59, 21 Oct 2003 (UTC)
      • How can the number of observers be assessed? The size (and seriousness) of the instituting body is more obtainable. I agree with you, broadly, though. 217.206.44.122 17:21, 21 Oct 2003 (UTC)
    • Delete. If we list every made-up holiday celebrated by 50 random people, there will be a lot of extra nonsense. Daniel Quinlan 08:46, Oct 21, 2003 (UTC)
    • I propose to merge into Pi Day - unless that one is also a deletion candidate, that is. Andre Engels 08:56, 21 Oct 2003 (UTC)
    • agreed, merge with Pi day. ping 09:13, 23 Oct 2003 (UTC)
    • Merge with Pi Day - which should be kept, real day. -- Jake 14:26, 24 Oct 2003 (UTC)

merged. All is well with the world. Martin 21:18, 24 Oct 2003 (UTC)

  • Well, better, I suppose. Hurumph. It's still not clear what should be done about 'days' in general. Do we need criteria, or is consensus enough? There are a lot of silly invented ones out there (far worse that this one, I'll grant you). MrJones 00:58, 25 Oct 2003 (UTC)
  • I've raised a similar point on Wikipedia_talk:Deletion_policy. MrJones 01:17, 25 Oct 2003 (UTC)
  • I'm sorry, this whole Pi Day page is nonsense. It is not an official day recognized by any country or any major religion. I'm not sure joke articles belong in Wikipedia. Worse yet as a joke, it isn't even funny. Sour pickle 04:50, 22 July 2005 (UTC)
    • If it's nonsense to you because of it not being a religious or national holiday, I bring to your attention that there is another category of holidays, the geek holidays. There is a world beyond what is recognized by governments and religons. Nothing to be sorry about. --BrendanRyan 09:04, 22 July 2005 (UTC)
    • Even if I did think this page was a waste of time and space, it's nowhere near the waste that this whole arguement is. It's obvoise that Mr. Jones doesn't like this page, but there are definately more than "50 random people" that celebrate this day. I have gone to two different high schools, one in Indianna and one in California and I had multiple teachers in both schools that celebrated pi day. I'm a major celebrator (I mean major as in I decorate my house, make pi day shirts, eat lots of pies, and even memorize digits of pi) so I mention it to lots of people and you'd be suprised how many people have heard of it. Regardless, I think everyone just needs to calm down and let the page be.Nathan Wonnacott

I concure with my brother, Pi Day is more than just some random day someone thought up, I've been to schools in Indiana, California, and now Utah were Pi Day is observed. It is a legitimate holiday and is practiced by far more than the few math fanatics one would expect. Jared Wonnacott

[edit] The first Pi Day?

14 March, 1592? :D DX 03:03, Apr 11, 2004 (UTC)

[edit] Pi moment?

From the article:

Some, using a twenty-four-hour clock rather than a twelve hour clock, say that 1:59 PM is actually 13:59 and celebrate it at 1:59 AM instead.

Wouldn't a more accurate approach be to consider it as a 24-hour time, 3/14 15:92:65, subtract the hour from 92 to get 16:32:65, subtract the minute from 65 to get 16:33:05, aka 4:33:05 PM? Otherwise, you're wasting a digit, and making us stay up until 1:59 AM, which is gosh, a whole half hour away for me now! -- John Owens (talk) 07:29, 2005 Mar 14 (UTC)

lol this entry is probably one of the funniest on wikipedia. "Pi Day" -__- wooot math geeeeeeeeks! 142.58.101.46 21:18, 14 Mar 2005 (UTC)

amen, I must say, I've never enjoyed a page more than this. I love you guysNathan Wonnacott

teehee! Millyissa

[edit] POV problems

Calling 3.14 "Pi" and 22/7 "pi approximation" is awfully decimal-centric, especially since the latter is closer to the true value of pi. And the integer POV (pi=3) is nowhere to be seen. ;-) DDerby 11:06, 15 Apr 2005 (UTC)

Well, the question should be, "what do people who celebrate these days call them"? What names we think appropriate is irrelevant; this page should exist to encyclopedically record the event as celebrated. There doesn't seem to be much evidence presented that people do celebrate these days, though - all discussion seems to be along the lines of "wouldn't it be cool if...", not "this is celebrated by..." TSP 13:45, 22 July 2005 (UTC)
Hee. Thanks for the laugh. :)
I agree, although it would be fun to come up with all the days we could celebrate it, or should celebrate it, it is celebrated on March 14 by everyone I've heard of, if we get too caught up with our "we should"'s then we won't all celebrate together. It would be as if some people celebrated Christmas on April 6th because they belive that was when Christ was born. It would create a division in the holiday and ruin the season. Millyissa

[edit] Can you corroborate this?

"(in most non-english speaking parts of the world the pronounciation of pi does not correspond to pies or various drinks, in some languages it corresponds to urine)"

Is this true? - Ianneub 18:19, July 22, 2005 (UTC)

The original author has obscured his meaning in an attempt to appear genteel. His point was that the pronunciation of "pi" in many languages (including, as it happens, Greek) is "pee" rather than "pie". The argument is half-baked, however, since it is in any case extremely unlikely that those languages will include the other words referred to. Largely irrelevant. -- scwimbush 03:43, 11 March 2006 (UTC)

[edit] WikiProject Holidays

You may be interested in the WikiProject, WikiProject Holidays, a WikiProject that will focus on standardizing articles about Holidays. It has been around for quite some time, but I'm starting it up again, and would like to see some more members (and our original members) around the help out. Cheers. — Ilγαηερ (Tαlκ) 21:16, 21 August 2005 (UTC)

[edit] Ultimate Pi Day

Another potentially ultimate Pi day would be 3141 May 9, though it remains to be seen if Wikipedia will still be around by then. ;-)

At 26:54, if we've reformed our calendar, thank you. ~user:orngjce223how am I typing? 01:40, 7 January 2007 (UTC)

[edit] Another Pi Approximation Day

another good day would be March 14 2015, as one would write that in abbreviation as 3/14/15, and also it's a lot closer than the year 3141 ;]

I'm soooo excited! You guys are all invited to my 3/14/15 party! only like 8 years, 55 days, 12 hours, 38 minutes, 26.53589793238462643383... secondsNathan Wonnacott 21:21, 16 January 2007 (UTC)

[edit] Happy Pi Day 2006!

Happy Pi Day, everyone! JaredW! 12:19, 14 March 2006 (UTC)

Happy Pi Day back to you! Of course we all know that Pi are round, not square! :o) Erzahler 19:14, 14 March 2006 (UTC)

Happy Pi Day to all! We celebrated Pi Day today at my high school by selling pies. I helped organize it, along with the rest of the math team (this is pretty much the biggest thing we do all year); however there was not enough pie left during my lunch hour for me to buy. So I didn't get to eat any pie. Oh well. It was still a good Pi day. BirdValiant 21:48, 14 March 2006 (UTC)

[edit] Reversions of changes to the value

I checked this site: http://www.joyofpi.com/pi.html , and it seems the anons are right after all. Please don't revert the latest change. It is 3.14159265358. — Kimchi.sg | Talk 00:08, 16 March 2006 (UTC)

[edit] Changes on March 14, 2006

The anonymous editor User:129.97.83.220 added the claim that

Pi day was invented by the University of Waterloo.

I removed it for the moment. If it is false, it should not be in the article. If it is true, some documentation should be provided; in particular, I doubt that "the university" invented it. It may well have been a particular person (student, processor, staff?) or a particular office in that university. Again, if it is true, there must be some documentation.

I also removed User:70.29.101.177's description

In addition, the businesses ... of the Greater toronto area have started recognizing Pi day. The Pi-oneer Elvin Wong petitioned for months to implement a Pi day celebration.... To be considered an offical Pi day celebration, there must be a minimum of 5 people...

It certainly does not fit into the first paragraph of the article. (If it is true, there could be a subsection "pi day around the world.) Second, "for months" does not make sense if no year is given for Wong's action. But it sounds like something something made up in school one day.

Full text that I removed:

Pi day was invented by the University of Waterloo, which celebrates it annually by bestowing pie on its undergraduates. In addition, the businesses and commercial offices in the Richmond Hill area of Greater Toronto have started recognizing Pi day. The “Pi-oneer”, University of Waterloo graduate hopeful Elvin Wong, petitioned for months to implement a Pi day celebration in the work place. A 20-minute slice of time is taken starting from 1:59pm. To be considered an offical Pi day celebration, there must be a minimum of 5 people to make up the “crust” of the Pi day celebration. Over half of the members of the crust must be attending or be alumni of the University of Waterloo.

[edit] Removed alteration of "pi moment" date and time

I reverted the pi moment paragrah from this text, which was inserted by User:207.69.137.27:

The "ultimate" pi moment<ref>At least twice in the West, about a fortnight earlier for those countries (like Russia and the UK) that still used the Julian calendar in 1592.</ref> will occur on March 14, 5358, at 1:59 AM and 26 seconds. When written in American-style date format, this is 3/14,1:59:26, 5358 which corresponds to the value of pi to twelve digits: 3.14159265358.

I highly doubt that Americans write their date and time in MMDDHHmmSSYYYY format. — Kimchi.sg | Talk 08:02, 19 March 2006 (UTC)

[edit] Unrelated holidays in See also

I think that other unrelated holidays, namely White Day, Steak and Blowjob Day, and Ides of March, should not be listed in the See also section because they have nothing to do with Pi Day. They fall near the same calendar date but that's it. These other holidays are listed in March 14, which is where they belong. Jonathan Kovaciny 22:38, 23 March 2006 (UTC)

[edit] Has anyone considered...

celebrating Pi Day by watching the TV show Magnum P.I.? Cuz, you know, P.I., pi....

i think that pi day is a really cool thing. i am doing pi for a project so i am looking in to pi day.

[edit] Order of Pi Approximation Days List

Those who wish to add more pi approximation days, please keep them in order of their occurrence in the year.

[edit] AIMEE math competition-- on this day?

Does anyone know if the AIMEE math tests are traditionally held on this day? At my school, they had the competitions today, on the 13th of March... Abeg92contribs 00:30, 14 March 2007 (UTC)

[edit] Pi Equinox, Einstein's Birthday

Two things might be useful to add to this article:

  • At my middle school, we used to count down until the "Pi Equinox", 14 March at 1:59:26 pm. (I know it doesn't really work in 24h, but nobody would be up.)
  • Albert Einstein's birthday is — no way! — Pi Day.

[edit] Pi Across America

This is now the second time that User:OrangeMustang has added the Pi Across America link. These two times are the only edits he has made to the wiki. As a rule for myself, I don't go to any suspicious websites (I'm afraid of getting viruses and spy/adware), so I don't know if it is suitable or not. Is this website suitable to be included under external links, or is this just another case of spamming? --LuigiManiac | Talk 19:10, 19 March 2007 (UTC)

I, using FireFox with various extensions, felt comfortable enough to follow the link. The site has various pi-related topics, but is not really about Pi Day, so I removed the link. timrem 20:09, 19 March 2007 (UTC)
