History and Genealogy Reference Unit. Today, Americans are used to a calendar with a “year” based the earth’s rotation around the sun, with “months” having no relationship to the cycles of the moon and New Years Day falling on January 1. However, that system was not adopted in England and its colonies until Throughout history there have been numerous attempts to convey time in relation to the sun and moon. Even now the Chinese and Islamic calendars are based on the motion of the moon around the earth, rather than the motion of the earth in relation to the sun, and the Jewish calendar links years to the cycle of the sun and months to the cycle of the moon.

The Julian Calendar In 45 B. This calendar employed a cycle of three years of days, followed by a year of days leap year. When first implemented, the “Julian Calendar” also moved the beginning of the year from March 1 to January 1. By the ninth century, parts of southern Europe began observing first day of the new year on March 25 to coincide with Annunciation Day the church holiday nine months prior to Christmas celebrating the Angel Gabriel’s revelation to the Virgin Mary that she was to be the mother of the Messiah.

The last day of the year was March However, England did not adopt this change in the beginning of the new year until late in the twelfth century. Because the year began in March, records referring to the “first month” pertain to March; to the second month pertain to April, etc. In fact, in Latin, September means seventh month, October means eighth month, November means ninth month, and December means tenth month. Use of numbers, rather than names, of months was especially prevalent in Quaker records.

As the day progresses, the sun moves across the sky, causing the shadow of the object to move and indicating the passage of time.

The age of Earth is estimated to be 4. Following the development of radiometric age-dating in the early 20th century, measurements of lead in uranium-rich minerals showed that some were in excess of a billion years old. It is hypothesised that the accretion of Earth began soon after the formation of the calcium-aluminium-rich inclusions and the meteorites. Because the time this accretion process took is not yet known, and predictions from different accretion models range from a few million up to about million years, the difference between the age of Earth and of the oldest rocks is difficult to determine.

It is also difficult to determine the exact age of the oldest rocks on Earth, exposed at the surface, as they are aggregates of minerals of possibly different ages. Studies of strata —the layering of rocks and earth—gave naturalists an appreciation that Earth may have been through many changes during its existence. These layers often contained fossilized remains of unknown creatures, leading some to interpret a progression of organisms from layer to layer. Nicolas Steno in the 17th century was one of the first naturalists to appreciate the connection between fossil remains and strata.

In the midth century, the naturalist Mikhail Lomonosov suggested that Earth had been created separately from, and several hundred thousand years before, the rest of the universe. Lomonosov’s ideas were mostly speculative. In the Comte du Buffon tried to obtain a value for the age of Earth using an experiment: He created a small globe that resembled Earth in composition and then measured its rate of cooling.

Uses of Radiocarbon Dating Climate science required the invention and mastery of many difficult techniques. These had pitfalls, which could lead to controversy. An example of the ingenious technical work and hard-fought debates underlying the main story is the use of radioactive carbon to assign dates to the distant past. The prodigious mobilization of science that produced nuclear weapons was so far-reaching that it revolutionized even the study of ancient climates.

The radioactive isotope carbon is created in the upper atmosphere when cosmic-ray particles from outer space strike nitrogen atoms and transform them into radioactive carbon. Some of the carbon might find its way into living creatures. After a creature’s death the isotope would slowly decay away over millennia at a fixed rate. Thus the less of it that remained in an object, in proportion to normal carbon, the older the object was.

By , Willard Libby and his group at the University of Chicago had worked out ways to measure this proportion precisely. Their exquisitely sensitive instrumentation was originally developed for studies in entirely different fields including nuclear physics, biomedicine, and detecting fallout from bomb tests. Much of the initial interest in carbon came from archeology, for the isotope could assign dates to Egyptian mummies and the like.
