I confess to being a numbers nut. Having just entered the date on a form as 10/12/13, (it could have been 10 12 13 in boxes), it occurred to me that since the year 2003 we have at some point in the year had sequential numbers in the date i.e. 01/02/03 and that after tomorrow 11/12/13 we will not have this occur again until it is 01/02/03 in 90 years & 52 days time.
