Martes trece, bad luck in Spanish

Babbel.com is closing in on its first anniversary on Thursday, the 15th, when we will be launching an ‘Inside Babbel’ series chronicling a bit of the goings-on behind the scenes at the language-learning website. But we thought in the meanwhile we’d give you the heads-up on a slightly older anniversary today, which would be the biblical confusion of languages at the Tower of Babel, which ostensibly happened on a Tuesday, the 13th.
While Anglo-Saxon cultures tend to avoid unnecessary travel and watch their backs on Friday the 13th, in Spain, Latin America and Greece Tuesday is the day to look out for. As Martes (Tuesday) in Spanish is linguistically linked with Mars, the god of war and violence, its combination with number 13, long a bad luck número, is almost too much for some to take. According to wikipedia, there’s actually a condition called Trezidavomartifobia, a paralyzing phobia of Tuesday the 13th.
