An event may well have both a ''terminus post quem'' and a ''terminus ante quem'', in which case the limits of the possible range of dates are known at both ends, but many events have just one or the other. Similarly, ''terminus ad quem'' ("limit to which") is the latest possible date of a non-punctual event (period, era, etc.), while ''terminus a quo'' ("limit from which") is the earliest. The concepts are similar to those of upper and lower bounds in mathematics. These terms are often used in archaeological and historical studies, such as dating layers in excavated sites, coins, historical events, authors, inscriptions or texts wher ...
