A morbid fear of the number 13 or the date Friday the 13th.

Past disasters linked to the number 13 hardly help triskaidekaphobics overcome their affliction. The most famous is the Apollo 13 mission, launched on April 11, 1970 (the sum of 4, 11 and 70 equals 85 - which when added together comes to 13), from Pad 39 (three times 13) at 13:13 local time, and struck by an explosion on April 13.

Triskaidekaphobia is from Greek treiskaideka, triskaideka, thirteen (treis, three + kai,and + deka, ten) + phobos, fear.
In Christian countries the number 13 was considered unlucky because there were13 persons at the Last Supper of Christ. Fridays are also unlucky, because the Crucifixion was on a Friday. Hence a Friday falling on the thirteenth day is regarded as especially unlucky.
