1/1/11 is one format for expressing today’s date. 2011/01/01 is another one. 1st January 2011 is a third way. January 1, 2011 is a fourth way.
That is of course given you use the Gregorian calendar and you don’t live far east from me, where it’s already a new day when I post this post.
1/1/11 is not one of those days where we have the usual confusion between the American way of expressing a date using the sequence month/day/year opposite to the common straight forward European sequence being day/month/year.
But in a few hours when it’s 2/1/11 in Europe and some hours later when it’s 1/2/11 in North America we are confused.
So, data quality folks, remember putting your dates in a unique format starting from tomorrow the 2nd January 2011 or, if you like, January 2, 2011.
Happy New Unique Year.
