Statistically speaking -- we're doomed.

[leffe_brune]

The use of the Gregorian calendar and its leap year system results in a small statistical anomaly, that the 13th of any month is slightly more likely to fall on a Friday than any of the other six days. The figures are 688/4800 (43/300) which is .1433333..., being just slightly greater than 1 in 7.
