Wednesday 11th December 2013 – 11 12 13, a very special day!
It can, of course, be written as: n + 10 but it looks so much better as 11 12 13.
And, at ten past nine, it’ll be 9:10 11 12 13
You won’t get another day like this for some time – the next consecutive day will be 1 2 3, or the 1st February 2103 – so enjoy the day while you can.
