While studying in Oxford seven years ago—most likely in a fit of procrastination—I determined that the word billion can be spelled on a telephone keypad with the number 245-5466. As it turns out, 2455466 was also the Julian date of a certain September day in [the then-distant future year] 2010. I put a reminder in my Palm V and forgot about it. Thanks to an electronic calendar that doesn’t forget, I was just reminded…
That day is today.
Happy Billion Day, everyone!
(One could discount this event by pointing out it’s only the coincidence of a) Julius Caesar’s arbitrary selection of the calendar’s start date, as well as b) the arbitrary—though now standardized—mapping of Latin letters to the 10-digit keypad. I suppose we could also cite the rise of the decimal numeral system in this celebration as well; who knows what billion would map to on a hexadecimal phone keypad, or if we’d even care since 1,000,000,000 is much less elegant as 3B9ACA00 in hex. Then again, many of our declared holidays aren’t much less arbitrary.)
