Talk:Square Root Day

Extended

Since we're only looking at the last digits, then why would we exclude months 10, 11 and 12?

• Simple days: 01/01/01, 02/02/04, 03/03/09, 04/04/16, 05/05/25, 06/06/36, 07/07/49, 08/08/64, 09/09/81
• 10/10/100 (or every 00 year)
• 11/11/121 (or every 21 year)
• 12/12/144 (or every 44 year)

Sure, this loads the front of the century, but this is never going to be a "REAL" holiday anyway. It's all about mathematical amusement, with liberties taken.

Wouldn't this holiday become ridiculously spaced out toward the end of the century? For example it'd go from August 8, 2064 to September 9, 2081. Like 17 years difference. The next one after 2081 I guess would be January 1, 2101 as you'd start over.--T. Anthony 14:17, 23 October 2005 (UTC)

I highly doubt that this teacher is notable enough to be mentioned in the article. Chances are that he is not the only teacher to celebrate this holiday. --ʀ6ʍɑʏ89 20:36, 26 January 2006 (UTC)

Dear Korath, you posted on Pi day! how ironic.

If you are a teacher and celebrate this day please help make this article better Jeffklib 08:00, 7 August 2006 (UTC)

Shouldn't October 10, 2100, be considered square root day as well? True, it uses the last three numerals of the year instead of just two, but it would still work--at least, once ever millennium. —Preceding unsigned comment added by 66.161.195.194 (talk) 20:20, 5 March 2009 (UTC)

What about 4/5/2025? —Preceding unsigned comment added by 68.197.66.249 (talk) 22:23, 24 December 2009 (UTC)

And today is 3rd of March in 2009!

I come from Hong Kong and one of the TV news reported today. But there isn't much information about this special day on the Internet.--Pchackal (talk) 07:44, 3 March 2009 (UTC)

Is this day legit?

I was sure that the square root of 2009 was 44.821869662029940805417523722353, not 3. Seems like a stretch to make up this holiday. —Preceding unsigned comment added by Beevo (talk • contribs) 23:38, 3 March 2009 (UTC)

It seems a stretch to me, also, but that's the way its reported. — Arthur Rubin (talk) 13:55, 4 March 2009 (UTC)

The definition, as widely reported elsewhere, is that the month and the day are each the square root of the last 2 digits of the year. No stretch. Finell (Talk) 18:07, 5 March 2009 (UTC)

The Flaw of Square Root Day

Flaw # 1 Taking the square root of a number involves taking the number and then computing its square so the year MUST be listed first then the month and day for it to even make sense.

Flaw # 2 Taking the square root only invloves [sic] two numbers NOT Three like Year Month and Day. Teachers are overpaid!

Alternative but just as stupid: To have a square root day this year one should recognize August 1 because the square root of 81 is nine. —Preceding unsigned comment added by 209.190.181.9 (talk) 15:04, 4 March 2009 (UTC)

There is no flaw, regardless of whether it amuses you. Regarding your non-Flaw # 1, the definition, as widely reported elsewhere, is that the month and the day are each the square root of the last 2 digits of the year. Or, if you prefer, a day is a Square Root Day if and only if it satisfies both of the following conditions:

1. Numeral day of month is square root of last 2 digits of the year.
2. Numeral month is square root of last 2 digits of the year.

Regarding your non-Flaw # 2, 3 = √9 is a valid statement. Or, if you prefer, 3 is the solution to the equation x = √9. The order doesn't matter.

At least this (overpaid?) teacher managed to create a day that is widely reported in the press and reminds the public of a little bit of math. Lighten up! Finell (Talk) 18:36, 5 March 2009 (UTC)
