This year we are going to experience four unusual dates: * 1/1/11 * 1/11/11 * 11/1/11 * 11/11/11   Take the last two digits of your birth year. Now add the age you will be this year. And the result will be 111 for everyone. This year October will have 5 Sundays, 5 Mondays and 5 Saturdays. This happens only every 823 years.
