Of course when I said it would be a party for Unix time, the real world has to have a party for this time also!! (See re-post of Unix time party below)
Today at 11:11 and 11 seconds, the date and time will be a perfect same-number palindrome—that is, it will read the same backwards and forwards, using the same number. It will be 11:11:11 on 11/11/11, and that won’t happen again for another 100 years.
Naturally, it’ll happen again at 11 PM, for those that don’t observe military time.
