The age of tide is the delay, usually a day or two, between full and new moons (when the equilibrium semi–diurnal tide is maximum) and the following spring tides. This terminology was first used to refer to this phenomenon by English scientist William Whewell in 1843, although Defant referred to it as “spring retardation” (in 1961) and Wood later (in 1978) used the terms “age of the phase inequality” and “age of the diurnal equality” to refer to, respectively, the ages of the semi–diurnal and diurnal tides. This delay is caused by frictional energy dissipation in coastal seas, although a localized increase in the age of tide is also a good indication of resonances at a given location.
