I have no idea what the downvoters are disagreeing with, since they did not condescend to say why.
But I couldn't find a definitive discussion of the history of the different formats. 500-1100 AD) dates were written in full sentences (e.g. So the format yyyy-mm-dd became pretty common on official documents, manufacturing stuff or interfaces.
Is it just conventional, or is there an official 'British date standard' (like with metric and imperial, for example). "fifteenth day before the calends of April" -- Anglo-Saxon Chronicle) rather than using any kind of notation. I have no sources to quote as such, but personally prefer to use a logical format starting with the lowest unit (days) and ending with the highest (years), thus the 4th of July would be most logical (to me anyway) in European format as 04/07/13, not 07/04/13..
Instead of writing May-24, we simply change the “May” to “5” and write 5-24 or ⁵⁄₂₄.
That way it follows the natural language order and so requires no mental gymnastics to switch things around when speaking the date aloud. This isn’t usually any sort of problem because of universal consensus on how to interpret such things in the United States.
If you write day/month/year in America, you will not be understood.
Although I myself prefer the ISO notation, normal people do not use it in their daily affairs.I’ve deleted the rest of the material in case it was distracting the downvoters.- *if the sink is in the kitchen - it's a sink, but if it's in the bathroom it's a basin.Another huge difference that causes great confusion is writing the date.When you write the date in numbers British and American English differ.To write the date 7th of September 2007 a Brit would write dd/mm/yy (07/09/07) and an American would write mm/dd/yy (09/07/07). It's better to write the date in full (7th September 2007 or September 7th 2007). (Thanks to Hermine, Naveen and Sally for a couple of additions on the forum and Facebook.
