Today, that is Friday the 13th, in Poland and a dozen other countries is considered extremely unlucky. The fear of this day even has a name: paraskevidekatriaphobia , which comes from the Greek language. After decomposing this word into its prime factors, it turns out that it is a conglomerate of three words: paraskeví in Greek means friday, dekatreís simply thirteen, and phob í a is phobia, or fear. Despite the Greek origin of the word, it is worth knowing that, paradoxically, in Greece, Friday the 13th is not considered a particularly bad day, and it is Tuesday the 13th ( τρίτη και dekatris ), which translates to "Tuesday and the 13th". This is a special way to highlight this distinctive day.
It's better to watch out for black cats too ;-)
The link between Tuesday the 13th and an exceptionally unlucky day has its roots in Greek history. Tuesday, May 29, 1453 is one of the most important dates not only in Greek but also in European history. On that day, the troops of the Ottoman Empire under the command of Mehmed II took Constantinople, which gave the Turks control over this part of the Mediterranean basin, but also opened the way to further conquest of Europe. Constantinople, or today's Istanbul, still belongs to the Turkish state. But you probably ask where is the unlucky 13 on this date? Well, we'll find it in the year ... the sum of the numbers 1 + 4 + 5 + 3 gives just 13.
Another example of an unlucky Tuesday is April 13, 1204, when the soldiers of the 4th Crusade broke the defense of Constantinople, slaughtered its inhabitants and then plundered incredible amounts of silver and gold, destroying this city in the process. According to historians, the scale of these events exceeded the examples encountered.
