Petek

Petek is a surname of South Slavic origin, found primarily in Croatia and Slovenia. The name derives directly from the word petek, meaning "Friday" in both Slovene and Croatian, which itself comes from the Slavic root pęt- meaning "five" (Friday being the fifth day of the week in Slavic counting, where Monday is counted as day one).

Etymology

The surname belongs to a category of European surnames derived from names of days of the week, often given to a child born on that day or to a servant associated with a particular weekday. In the South Slavic context, Petek mirrors similar surnames in other Slavic languages: for instance, the Polish surname Piątek (also meaning "Friday") and its dialectal variant Piontek represent the same pattern in Poland. This wide areal distribution points to a common Slavic onomastic tradition rather than independent coinage.

Notable Bearers

While no extensively documented notable individuals are recorded in standard encyclopedias, the surname Petek is established in Croatia and Slovenia. According to Internet searches, bearers participate in various public life domains, from journalism (e.g., Dario Petek in Slovenia) to football (e.g., Josip Petek in Croatia), though these are not verified by the brief's sources. The surname also appears in present-day Turkey, likely introduced during the Ottoman period or through more recent migration of Balkan peoples.

Variants and Related Names

The same calendrical concept gave rise to other slavic day-names, such as the Polish Piątek (Friday) and the less common Piontek, which is a regional variant. In Slovenian, the female counterpart of the surname is Petkovka, while also exists Petek could be a masculine personal name as in the Slovene noun pẹ́tek.
