Third Friday 13th of 2012

If it seems like Friday 13^th is coming round more often than usual, that’s because 2012 has three of them altogether – and these three days are 13 weeks apart.

When a leap year starts with a Sunday, that year will have a combination of three Friday 13ths, spaced exactly 13 weeks apart, in January, April and July.

This happens three or four times a century, following a 28 year cycle. The last such year was 1984 and the next one will be 2040.
