Today’s an international prime day
- adorable 13y agoSo today is an international prime day because 291113 112913 20131129 are all primes Today could also have been a "perfect prime day" if MM, DD, YY and YYYY had been prime (in addition to the above). But it's not the case... 11 -> is prime 29 -> is prime 13 -> is prime 2013 -> not prime (3 x 11 x 61) Too bad! We will have to wait another 16 years before we have a perfect prime day...
- ruttiger 13y agoya, but each of the factors of 2013 is prime, so that's gotta mean something, right?
- PeekPoke 13y agoNot prime here in the UK where we write our dates DDMMYYYY.
- JonnieCache 13y agoIn order of increasing duration, so you get to the most important information first. The correct order.
- johndcook 13y agoI like ISO format because then alphabetical order corresponds to chronological order. Y-M-D and D-M-Y both have their advantages. Unfortunately my compatriots have standardized on M-D-Y, a convention that has no advantages that I can think of.
- chrisdevereux 13y agoFor some reason, I'm now thinking about programming for a 'middle-endian' CPU. Maybe it was a compromise between big and small.
- Edvik 13y agoWhile not really useful in any computer sense, M-D-Y matches common English spoken construction "January 4th, 2015" is 1-4-15
- BerislavLopac 13y agoYou mean common American English. The rest of the world is using 4th January, 2015.
- vishnumenon 13y agoI've always found M-D-Y apt for many use-cases, because I often know exactly which year is being referred to - I just need to know the month and day. With M-D-Y, that information is immediately presented. It seems like a decent compromise.
- adambard 13y agoMy favorite format is YYYY-MMM-DD. That is, year, 3-letter (english) month, day (i.e. 2013-Nov-29). Only works for people that know the english names for dates, but eliminates ambiguity about which is the day and which is the month.
