All over the world, Kaljan (Калжан 
, กัลยาณ 
, Kaljan 
) is quite a rare unisex given name. The first name Kaljan is habitual in Kazakhstan, where it is quite a rare epicene name, Azerbaijan, where it is quite a rare boy's name, and Thailand, where it is a very rare predominantly feminine, but scarcely male name. Much less frequently, Kaljan is the last name as well as the forename.
