Some scientists prefer the terms chronometric or calendar dating, as use of the word "absolute" implies an unwarranted certainty of accuracy.Absolute dating provides a numerical age or range in contrast with relative dating which places events in order without any measure of the age between events.
It only sequences the age of things or determines if something is older or younger than other things.
Using "0 days before/after today" means current date.
Relative dating is a dating method that used to determine determine the relative ages of geologic strata, artifacts, historical events, etc.
Further, he proposed that wherever un-contorted layers were exposed, the bottom layer was deposited first and was, therefore, the oldest layer exposed; each succeeding layer, up to the topmost one, was progressively younger.
The concept is considered by uniformitarian geologists to be a major breakthrough in scientific reasoning by establishing a rational basis for relative time measurements.
Fossils is an identification event which rotates with Rocks and Minerals every two years.
