Odd Day is coming Thursday, 5/7/9. Three consecutive odd numbers make up the date only six times in a century. This day marks the half-way point in this parade of Odd Days which began with 1/3/5. The previous stretch of six dates like this started with 1/3/1905---13 months after the Wright Brothers' flight.
I celebrate pi day (3/14, or March 14th) every year with the math society, so I'm no stranger to mathematical holidays. But I'd never thought about odd days before! Seems like a fun thing to celebrate. Especially since, as women in science and engineering, we're often viewed as odd ourselves!
Rejoice in your oddness! Happy Odd Day!
