In the entire world, ประจัน (Prachan 
, ประจัน ) is a rare predominantly masculine, but scarcely female first name. The forename ประจัน is characteristic of Thailand, where it is a rare principally boy's, but very infrequently feminine name, and India, where it is an extremely rare boy's name. Much less frequently, ประจัน is the last name as well as the forename.
