A period of time, extended or shorter, extraordinary for situations of wonderful subsequent impact; a unforgettable period; as, the epoch of maritime discovery, or in the Reformation.

The Julian and Gregorian calendars use as epoch the Incarnation of Jesus as calculated during the 6th century by Dionysius Exiguus.[4] (Subsequent analysis has shown that this instant is about 4 years once the finest estimate for the day of delivery of Jesus.
When moments prior to the epoch need to be represented, it is actually popular to employ precisely the same procedure, but with damaging figures.
Alternatively, enough time-varying astronomical quantity is often expressed as a constant, equivalent for the measure that it experienced at the epoch, leaving its variation over time for being specified in Various other way—for instance, by a table, as was frequent over the 17th and 18th hundreds of years.
Personal computers don't frequently retailer arbitrarily massive figures. As a substitute, Each and every variety stored by a computer is allotted a fixed quantity of Area.

It could be viewed the date in the coordinate program need not be the same as the epoch from the astronomical quantities on their own. But in that situation (other than the "equinox of day" situation described above), two dates will probably be linked to the data: a person date will be the epoch for the time-dependent expressions supplying the values, and the opposite day is that in the coordinate procedure during which the values are expressed.
