Around the globe, Vihan (Vihan 
, วิหาร ) is quite a rare epicene first name. The first name Vihan is characteristic of Thailand, where it is a rare primarily male, but scarcely female name, Kuwait, where it is a rare boy's name, and Saudi Arabia, where it is a very rare male name. In absolute terms, it is commonest in India, Thailand, and Saudi Arabia. Much less frequently, Vihan is the last name as well as the forename.
