Well, 12 to be more accurate.

For most people, there are 12 date/time combinations that are fairly unique.

Using a 24-hour clock, these are:

The first of these sticks in my mind as 2001,2001,2001 was the Birthday of a friend, Gillian who I was very fond of.

I haven't thought of anything to match up with 2002,2002,2002 - 2007,2007,2007 yet but will have a look back to see if anything matches.

The next will be 2008,2008,2008 - so where will you be on the 20th August this year at 20:08 hrs?

The last time these date/time combinations came up was between 1901 to 1912 and I for one wasn't around in those days, and since the next 12 will be 2101 to 2112 I'll most likely be dead by then.
