Earlier this year I noticed that the date could be written as 1.13.13 [January 13, 2013] and

the day and month multiplied gave the year [modulo 100] Thirteen being both prime and

greater then the number of months, this is the only such date in 2013.

What year this century contains the most such dates?

What I tried to convey by modulo 100 simply was 2013 becomes 13, which then is the straight product of 1 and 13.
Being prime and all that is not a requirement, just dates like 5/12/60.

You've opened up a richer set of possibilities, which I will now go back and work through.
Thanks.
