Tenday

A tenday was a Faerûnian unit of time equal to 10 days. The Calendar of Harptos divided the thirty-day months into three blocks of ten days each, or simply put, "tendays". The word was used interchangeably with the Earthly term "week".

Other terms used synonymously with tendays included eves, domen, hyrar, and rides. As of 1367 DR, "rides" was the preferred term throughout Cormyr and the Dalelands.
