In all the world, Chethana (Chethana 
) is quite a rare mostly female, but seldom boy's first name. The forename Chethana is characteristic of Sri Lanka, where it is quite a rare gender-neutral name, India, where it is a very rare predominantly feminine, but very infrequently boy's name, and the United States. Much less frequently, Chethana is the last name as well as the forename.
