All around the world, Кальва (Calva 
, Кальва 
) is a rare epicene forename. The given name Кальва is characteristic of Israel, where it is a rare principally female, but very seldom boy's name, Italy, where it is a very rare female name, and the United States, where it is a very rare unisex name. Not in comparison with a country's population, this name is the most popular in India, Israel, and the United States. Predominantly, Кальва is the last name as well as the forename.
