Haide is a name of Greek origin, derived from the Greek word "haides," which means "the infernal regions." It has also been interpreted to mean "dark-haired" or "of the dark earth." The name Haide was popular in ancient Greece and was used for both male and female children. In some variations of the name, it is spelled Hades, after the Greek god of the underworld who shared his name with the region he ruled over.
The name Haide appears to have had fluctuations in popularity over the years, with a notable peak between 1994 and 1996, where it saw an average of 13 births per year. However, since then, its usage has generally declined, with only a few instances occurring each year from 2005 onwards.
