to date (e. g . a cheque ) before the actual date,

(of something new) to cause (something else) to become old-fashioned or obsolete

to undergo or cause to undergo a chemical reaction with oxygen , as in formation of an oxide

to grant ( lands ) by subinfeudation

the system of marking products with the date when they were packed

Carbon dating is a system of calculating the age of a very old object by measuring the amount of radioactive carbon it contains.

a method of dating objects, remains , etc, by comparison and correlation with other sites and levels

An agency is a business which provides a service on behalf of other businesses.

Speed dating is a method of introducing unattached people to potential partners by arranging for them to meet a series of people on a single occasion .

the use of computers by dating agencies to match their clients

a service that provides introductions to people seeking a companion with similar interests

the determination of the age of an artifact, bone , rock, etc. based on the known rates of decay of radioactive isotopes of various elements

a technique for determining the age of organic materials, such as wood, based on their content of the radioisotope 14 C acquired from the atmosphere when they formed part of a living plant. The 14 C decays to the nitrogen isotope 14 N with a half-life of 5730 years. Measurement of the amount of radioactive carbon remaining in the material thus gives an estimate of its age

any method of dating material based on the decay of its constituent radioactive atoms , such as potassium-argon dating or rubidium-strontium dating

a technique for determining the age of organic materials, such as wood, based on their content of the radioisotope 14 C acquired from the atmosphere when they formed part of a living plant. The 14 C decays to the nitrogen isotope 14 N with a half-life of 5730 years. Measurement of the amount of radioactive carbon remaining in the material thus gives an estimate of its age

the dating of samples of minerals by comparing the tracks in them by fission fragments of the uranium nuclei they contain, before and after irradiation by neutrons

If something dates back to a particular time, it started or was made at that time.

If something dates from a particular time, it started or was made at that time.

a technique for determining the age of minerals based on the occurrence in natural potassium of a small fixed amount of radioisotope 40 K that decays to the stable argon isotope 40 Ar with a half-life of 1.28 × 10 9 years. Measurement of the ratio of these isotopes thus gives the age of the mineral

to determine the age of an organic object by examining the relative proportions of the carbon isotopes carbon-12 and carbon-14

a date for two couples

a technique for determining the age of minerals based on the occurrence in natural rubidium of a fixed amount of the radioisotope 87 Rb which decays to the stable strontium isotope 87 Sr with a half-life of 4.7 × 10 11 years. Measurement of the ratio of these isotopes thus gives the age of a mineral, for ages of up to about 4 × 10 9 years
