Similarly, a terminus ad quem 'limit to which' is the latest possible date of a non-punctual event (period, era, etc.
The terminus post quem for the burial would be the latest date established with certainty: in this case, 1595.
An archaeological example of a terminus ante quem would be deposits formed before a historically dateable event, such as building foundations that were partly demolished to make way for the construction of a city wall.
If it is known that the wall was finished in 650, then the foundations must have been demolished in 650 or earlier; all that can be said from the evidence is that it happened before the known event.
In a modern context, dated images, such as those available in Google Earth, may establish termini.
