Today was 10-10-10. I saw on the news tonight that lots of people got married today thinking the date lucky or memorable. If you want to plan ahead, there will be an 11-11-11 next year and 12-12-12 the following year. I think 12-12-12 is after the end of the world date of 2012, so you might want to plan for the 11-11-11 date to be sure.
