A month later, here we go again - yet another Friday the 13th.
As I have already described superstition behind this date extensively in my February post, today I will pay more attention to the statistics.
This year, the year of 2009, we can experience the total of three Fridays with this magic number; there is one more in store for us comes November. This is the highest number of Fridays the 13th possible in a year. The lowest amount is one, just like it was last year, in 2008 (only one in June). There is always at least one Friday the 13th in any given year and no more than three.
Next year, in 2010, again only one Friday the 13th will occur, and that will happen in August.
The next time around we will get three lucky Fridays will be in 2012 and these will occur in January, April and July.
The same sequence as this year (February, March, November) will happen in 2015.
There is a particular sequence of how Fridays the 13th are distributed and this sequence repeats every 28 years:
2001 April, July
2002 September, December
2004 February, August
2006 January, October
2007 April, July
2009 February, March, November
2012 January, April, July
2013 September, December
2015 February, March, November
2017 January, October
2018 April, July
2019 September, December
2020 March, November
2023 January, October
2024 September, December
2026 February, March, November
The longest period of time possible without a Friday the 13th is 14 months. Interestingly, statistically the date of the 13th occurs more often on a Friday than any other day of the week, tightly followed by a Sunday and a Wednesday (as a tie).

The Uruguayan rugby team’s plane crashed in the Andes mountain range on Friday, 13 October, 1972.
Last month, one of our students flew to London on Friday the 13th and there was a problem with the plane; after taxing away and preparing for the take off on the runway, the pilot announced that one of the engines would not start and the plane had to return to the gate.
The student told me he truly contemplated (for the first time ever in his life) to ask to be allowed to leave the plane. But eventually he found comfort in the notion that the pilots and the ground crew must know what they are doing.
After 40 minutes the engine was repaired and they took off without problems.;)
