Absolute dating is the process of determining an age on a specified chronology in archaeology and geology. Some scientists prefer the terms chronometric or calendar dating , as use of the word "absolute" implies an unwarranted certainty of accuracy. In archaeology, absolute dating is usually based on the physical, chemical, and life properties of the materials of artifacts, buildings, or other items that have been modified by humans and by historical associations with materials with known dates coins and written history. Techniques include tree rings in timbers, radiocarbon dating of wood or bones, and trapped-charge dating methods such as thermoluminescence dating of glazed ceramics. In historical geology , the primary methods of absolute dating involve using the radioactive decay of elements trapped in rocks or minerals, including isotope systems from very young radiocarbon dating with 14 C to systems such as uranium—lead dating that allow acquisition of absolute ages for some of the oldest rocks on Earth.

Dates are a very important part of historical and genealogical research, but they also aren't always as they appear. For most of us, the Gregorian calendar in common use today is all we encounter in modern records. Eventually, however, as we work back in time, or delve into religious or ethnic records, it is common to encounter other calendars and dates with which we aren't familiar. These calendars can complicate the recording of dates in our family tree, unless we can accurately convert and record the calendar dates into a standard format, so that there is no further confusion.
