For the mathematically challenged, Thursday’s date, 5/7/09, is one of only six this century that will feature three consecutive odd numbers.
Numbers lovers say the rare occurrence is an excuse to celebrate.
“The previous stretch of six dates like this started with 1/3/1905 — 13 months after the Wright Brothers’ flight,” said Ron Gordon, the Redwood City teacher who enthusiastically promotes these numerical holidays, like Square Root Day on 3/3/09.
Gordon is offering a prize of $579 to those who celebrate the date with the most zeal or who get the most people involved in an Odd Celebration.
