One [[folk tradition]] in English is the widespread use of "Sabbath" as a synonym of midnight-to-midnight "Saturday" (literally, [[Saturn]]'s day in at least a dozen languages): this is a simplification of the use of "Sabbath" in other religious contexts, where the two do not coincide. (Using midnight instead of sundown as delimiter dates back to the [[Roman Empire]].) In over thirty other languages, the [[week-day names|common name]] for this day in the [[seven-day week]] is a cognate of "Sabbath". "[[Sabbatini]]", originally "Sabbadini", often "Sabatini", etc., is a very frequent Italian name form ("[[Christodoulos Sabbatos|Sabbatos]]" is the Greek form), indicating a family whose ancestor was born on Saturday, Italian ''sabato''; "Domenico" indicated birth on Sunday.

In [[vampire hunter]] lore, people born on Saturday were specially designated as ''sabbatianoí'' in [[Greek language|Greek]] and ''sâbotnichavi'' in [[Bulgarian language|Bulgarian]] (rendered in English as "Sabbatarians"). It was also believed in the [[Balkans]] that someone born on a Saturday could see a [[vampire]] when it was otherwise invisible.
