Today’s date written in MM/DD/YY format uses 2 digits only. It already has happened twice this month and will not happen again in 2020.

Now read my question carefully and provide the exact answer:
How many such “thrifty” dates exist in the period between 01/01/00 and 09/09/99 (both dates included) that less than 3 digits suffice to write them ?

To amplify the power of the moment try to post your comments close to 20:20 !
