Radiometric or isotopic dating.
Absolute
Through Radiocarbon dating, the age of an object can be determined by using the properties of radiocarbon, a radioactive isotope of carbon. This method was invented by Willard Libby in the late 1940s.
Carbon dating is used to determine the age of various artefacts of a biological origin up to about 50,000 years. More ancient rocks can be dated by measuring the amount of decay of radioactive elements which may be present and is generically known as radiometric dating.

So you can find out how old your mom is. Roast!!!
This is known as radiometric dating.
Radiometric dating. Uses the property of elements decaying into other elements.
Archeologists determine how old an object is, by using Carbon Dating.

It is a dating method in geology based on natural fission of U238 to determine the atomic displacement (tracks) counts to determine age of material or volcanic deposits.
The radioactive decay of carbon, called "Carbon 12 dating". It isn't perfect, but it is usually accurate to within about 1,500 years, which makes it a very useful tool.
Radiocarbon dating is only accurate for objects up to about 50,000 years old, as the amount of carbon-14 left in the sample becomes too small to measure accurately beyond that point. Beyond this age limit, other dating methods such as potassium-argon dating or luminescence dating may be used to determine the age of older objects.
