Full Version: happy fibonacci day 5/8/13

Today on 5/8/13 at 21:34:55.89 the entire clock will be composed of Fibonacci numbers. Not as cool yet as PI day, which happens every year. I believe this may be the last time this century the d/m/y h/m/s.ss will all work without some kind of conversion.

(adjusts pocket protector)

And not just any Fibonacci numbers. Consecutive ones. This will be the last time ever that that will happen.

Nope! Next 05/Aug it will happen again down here, in many European countries and in a lot of other places elsewhere :-)

In theory it will happen again on 1/1/02 at 03:05:08.13, but that's almost 89 years (another fibonacci number!) from now. Haley's comet will come before then!

Why stop there? One can go forever: 21:34:55.89144233347580927...

It is sort of cheesy to mix the several radix systems on the front of this representation, plus ignore the 20 part of 2013. We'll all have to wait until 1.1.2358 13:21:34.5589144... ad infinitum to get the full year part right. I just marked it in my Android's calendar so I don't miss it.

I don't think it's as much fun as International Talk Like A Pirate Day. (Pirate is not related to Pi.)

We don't have to wait that long if we just want the calendar portion. Maybe by 8/13/2134 we'll be on a decimal time system so the clock can say 5589...

I concur. Actually, it will happen at 5.8.13 in
all European countries (yes, even in the UK ;-) ), Russia, India, whole Latin America, etc. See p. 47. Just a few folks care about May 8th really ...

The same applies to the real Pi Day, 22/07 :-)

Only if time is continuous. Is it? Otherwise one could've gone up to about the 40th decimal place. Either way that elusive moment is gone forever...
