What is ‘Triskaidekaphobia’?

‘Triskaidekaphobia’ is a word that arises from the greek tris meaning three, and deka meaning ten, i.e. thirteen, and phobia meaning fear. Triskaidekaphobia thus means the fear of the ‘number thirteen’. In western culture, the number thirteen is often associated with ill luck. Many hotels in the western countries have no thirteenth floor, and many streets are avoided being given the number thirteen.

Is it Friday, the 13th?

If 1st is a Sunday, then 8th is also a Sunday because 8 = 1 + 7. Then 9th, 10th, 11th and 12th are respectively Monday, Tuesday, Wednesday and Thursday. Hence, 13th is Friday. If one considers ‘Friday, the 13th’ to be a bad omen, one should not be happy with the first day of the month being a Sunday, thus a holiday.
