The numerical format for the day before yesterday was 11-17-1999. All of the digits are odd. The next Odd day will be 11-19-1999 (which is today). The next Odd day after that will be 1-1-3111 — which is well over a thousand years away, which we will never see. Days such as 4-13-89 have both even and odd digits, thus, it is neither odd nor even. The next even day will be 2-2-2000 — the first one since 8-28-888. So, now you have a reason to celebrate this Friday as it'll be your last odd day on Earth! Have a nice odd day!
