See Duller for a discussion of the options being considered.After the Gregorian calendar was established throughout most of the world, atomic clocks have allowed us to adjust our modern calendars with leap seconds to correct for the slowing spin of our planet and other corrections.

Radiocarbon dates after 1950 are virtually useless unless and until we can figure out a way to calibrate for the excessive amount of carbon still increasing in our atmosphere.

Nonetheless, 1950 is a very long time ago now--should we adjust the starting point to 2050?

Radiocarbon dating was invented in the late 1940s, 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). The problem is, of course, that CE and BCE still use the putative date of the birth of Christ as the reference points for its numbering system: the two years 1 BCE, 1 CE are equivalent to 1 BC, 1 AD.

The term ‘to date’, for instance, has a variety of meanings, and confusion about the dating of rock art (or the dating of archaeological remains, for that matter) initially stems from this ambiguity.

As a noun, ‘date’ may refer to the date shown on a coin, book or building, presumably representing the time of minting, printing or completion, i.e. But it may alternatively refer to a time period of some considerable duration (e.g.

Tree rings, which record the amount of atmospheric carbon in their rings, are used to calibrate radiocarbon dates. However, a major disadvantage with using BP is--the present year, of course, changes every twelve months.
