What does the name Day mean?

The Day surname has English, Welsh and Scottish roots. In Scotland and Wales it is sometimes used as a patronymic, a derivation of those who are the son or descendant of Dai (a Welsh diminutive of Dafydd) or David. More prevalently, in England Day comes from the Middle English 'Deye' (dairy-servant), and is occupational. This version of the Day surname would be given to those who made their living as dairy workers, and their descendants.
