This year we have four memorable and unusual dates:
1/1/11,........ 11/1/11,....... 1/11/11,...... 11/11/11,....and that's not all. Take the last two digits of the year you were born in and the age you will be this year, and the result will add up to 111 for everyone :!:
Also, this year, in October we had 5 Sundays, 5 Mondays, and 5 Saturdays. This happens only once every 823 years.
