A QUO

A term used, with the correlative ad quern, (to which,) in expressing the computation of time, and also of distance in space. Thus, dies a quo, the day from which, and dies ad quern, the day to which, a period of time is computed. So, terminus a quo, the point or limit from which, and terminus ad quern, the point or limit to which, a distance or passage in space is reckoned. Example, in the computation of time, the day a quo is not to be counted, but the day ad quem is always included. A court a quo, the court from which an appeal has been taken; a judge a quo is a judge of a court below.
