The initials BP or bp and rarely B. While BP is also used generally as an imprecise estimate of an age of an object or event, the use of it in science was made necessary by the quirks of the radiocarbon methodology. Radiocarbon dating was invented in the late ‘s, and within a few decades, it was discovered that while the dates retrieved from the method have a sound, repeatable progression, they are not a one-to-one match with calendar years. Most importantly, researchers discovered that radiocarbon dates are affected by the amount of carbon in the atmosphere, which has fluctuated greatly in the past for both natural and human-caused reasons such as the invention of iron smelting , the Industrial Revolution , and the invention of the combustion engine.
Tree rings , which keep a record of the amount of carbon in the atmosphere when they are created, are used to calibrate or fine-tune radiocarbon dates to their calendar dates.

The most commonly used system of dating things in history is the one which we use are known as A.D (short Anno Domini, and meaning the Year of our Lord).
Dating techniques are procedures used by scientists to determine the age of rocks, fossils, or artifacts. Relative dating methods tell only if one sample is older or younger than another; absolute dating methods provide an approximate date in years. The latter have generally been available only since Many absolute dating techniques take advantage of radioactive decay , whereby a radioactive form of an element decays into a non-radioactive product at a regular rate.
Others, such as amino acid racimization and cation-ratio dating, are based on chemical changes in the organic or inorganic composition of a sample. In recent years, a few of these methods have come under close scrutiny as scientists strive to develop the most accurate dating techniques possible. Relative dating methods determine whether one sample is older or younger than another. They do not provide an age in years.
Before the advent of absolute dating methods, nearly all dating was relative. The main relative dating method is stratigraphy. Stratigraphy is the study of layers of rocks or the objects embedded within those layers. It is based on the assumption which nearly always holds true that deeper layers were deposited earlier, and thus are older, than more shallow layers.
The sequential layers of rock represent sequential intervals of time. Although these units may be sequential, they are not necessarily continuous due to erosional removal of some intervening.
All of us tend to use the most significant dates in our lives as reference points for all the others.

They replaced the Roman stone buildings with their own wooden ones, and spoke their own language, which gave rise to the English spoken today. The Anglo-Saxons also brought their own religious beliefs, but the arrival of Saint Augustine in converted most of the country to Christianity. The Anglo-Saxon period lasted for years, from to , and in that time Britain’s political landscape underwent many changes.
The early settlers kept to small tribal groups, forming kingdoms and sub-kingdoms. By the ninth century, the country was divided into four kingdoms – Northumbria, Mercia, East Anglia and Wessex. Wessex was the only one of these kingdoms to survive the Viking invasions.
