Ron Gordon, the California teacher who founded and promoted Square Root Day reminds us that Thursday is another math holiday, Odd Day! The calendar date (as written by people in the US) will be 5-7-9, which only happens once a century. Odd Days happen six times a century. It's a day to take the opportunity to do something odd. In celebration, there's another contest, with $579 up for prizes. Get all the details at the Odd Day website. Link -Thanks, Ron!

The next time to celebrate will be 9/9/9
(three identical; where the square root is odd and prime) and then 11/11/11 (three identical primes).
I fondly remember 1/1/1, 3/3/3, 5/5/5, 7/7/7.... now those were some good identical prime parties.

Not quite right. It was the foreigners (The Normans) who built the castles.
Oh, because none of it is correct, that will be why.
If the writer of it is British then she lives in a totally different Britain to the rest of us (even allowing for the passage of time).
