Monday is Jan. 10, 2011. In numerical notation, it’s 1-10-2011, the first of two “palindrome dates” in the new year – dates that can be read the same, backwards or forwards. The next one will fall on Nov. 2, 2011, or 11-02-2011. After that, the next year with two palindrome dates is 2021, on Jan. 20 and Dec. 2. That’s the last year in this century with two palindrome dates in the month-day-year format, according to Prof. Aziz S. Inan, at the University of Portland.

Actually, I would argue with that. If a person is going to arbitrarily assign a '02' to November 2, then why not assign a '01' to the January (month) numerical notation?
Thus, Monday's date should be, in numerical fashion, be written (in base 10 AND in Arabic numerals) 01-10-2011, which is NOT palindromic.
And it is palindromic ONLY in American usage. In other English-speaking countries, the date is normally written date-month-year, thus Monday would be written as 10-1-2011, or 10-01-2011, and thus definitely NOT palindromic (1-10-2101, or 11-02-1001).
If you are going to be consistent, then maybe Tuesday's date should be written as 1-11-11? That is palindromic (somewhat, if you don't pay attention to where the dashes are located). The TRUE palindromic numeric expression within the next decade would be 11-11-11, IMO.
FR: Dr. Inan is well aware of the variants: http://bit.ly/gW4EQS ... and he has worked out all the palindrome dates in each, including the day-month-year format. We had space to refer only to the month-day-year format.

Which only goes to show, interpretations of EVERYTHING vary.
When I enlisted, the Army expressed the date in YYYYMMDD format, absent any dashes at all - which makes all sorts of things interesting when I unthinkingly use that date format as a civilian - and makes 2 Nov 2011 a palindrome: 20111102 while also (at first glance) eliminating palindromic dates after 2 Dec 2012 until 21011012 (12 Oct 2101). (I think.)
FR: It's also a good format for filing Word files in chronological order, as in 2011.01.10.weatherstory.doc
