Thursday (i /ˈθɜrzdi/ or /ˈθɜrzdeɪ/) is the fourth day of the week according to the ISO 8601 international standard adopted in most western countries. In countries that use the Sunday-first convention and in the Judeo-Christian calendar it is the fifth day of the week. It falls between Wednesday and Friday. The name is derived from Old English Þūnresdæg and Middle English Thuresday, which means "Thunor's day".
