Beware the Ides of March

2011 (http://www.bbc.co.uk/news/uk-england-london-12749912)

March 15, 2012 will represent a year to the day that the Olympic countdown clock stopped at 500 days, 7 hours and 6+ minutes... or that is to say, 500 days and 6 hours and 66 minutes.

March 15, 2012 - the Ides of March.
