Today is November 11, 2011, aka, 11-11-11 in the Gregorian calendar.

It’s the fourth, and last of such numerical alignments this year, the others being 1-1-11, 1-11-11, and 11-1-11.

The next time 3 identical numbers will appear in a date is 12-12-12 next year.  After that, it won’t happen again until 01-01-01 in the year 2101.

November 11 is the 315th day of the year (316th in leap years) in the Gregorian calendar. There are 50 days remaining until the end of the year.

Although no overly exciting events occurred in the history of 11-11-11, perhaps the most significant event that occurred on November 11 happened on the eleventh hour of the eleventh day of the eleventh month in 1918, when a temporary cessation of hostilities between the Allied nations and Germany went into effect, which is now generally regarded as the end of “the war to end all wars.”

A curiosity of mathematics, 111111 x 111111 = 12345654321.

A completely useless fact about 111: If you take the last two digits of the year you were born (using the Gregorian calendar) and add that to your age, the resulting number will be 111.
