Absolute dating is the process of determining an approximate computed age in archaeology and geology. Some scientists prefer the terms chronometric or calendar dating, as use of the word "absolute" implies an unwarranted certainty and precision. Absolute dating provides a computed numerical age in contrast with relative dating which provides only an order of events.
In archeology, absolute dating is usually based on the physical or chemical properties of the materials of artifacts, buildings, or other items that have been modified by humans. Absolute dates do not necessarily tell us precisely when a particular cultural event happened, but when taken as part of the overall archaeological record they are invaluable in constructing a more specific sequence of events.

Famous quotes containing the words absolute and/or dating:
“I learned early to understand that there is no such condition in human affairs as absolute truth. There is only truth as people see it, and truth, even in fact, may be kaleidoscopic in its variety. The damage such perception did to me I have felt ever since ... I could never belong entirely to one side of any question.”
—Pearl S. Buck (1892–1973)
“We go on dating from Cold Fridays and Great Snows; but a little colder Friday, or greater snow would put a period to man’s existence on the globe.”
—Henry David Thoreau (1817–1862)
