Around the globe, กลางวัน (Dayal 
, Dayam 
, Dayve 
) is a widespread primarily male, but scarcely feminine forename. The first name กลางวัน is characteristic of India, where it is quite a rare principally male, but very infrequently female name, Qatar, where it is quite a rare boy's name, and Oman. Not in comparison with a country's population, it is commonest in India, Bangladesh, and the Democratic Republic of the Congo. More frequently, กลางวัน is the last name as well as the forename.
