1. epactnoun

   the time (number of days) by which a solar year exceeds twelve lunar months; it is used in the calculation of the date of Easter

Samuel Johnson's DictionaryRate this definition:0.0 / 0 votes

1. Epactnoun

   A number, whereby we note the excess of the common solar year above the lunar, and thereby may find out the age of the moon every year. For the solar year consisting of 365 days, the lunar but of 354, the lunations every year get eleven days before the solar year; and thereby, in 19 years, the moon completes 20 times 12 lunations, or gets up one whole solar year; and having finished that circuit, begins again with the sun, and so from 19 to 19 years. For the first year afterwards the moon will go before the sun but 11 days; the second year 22 days; the third 33 days: but 30 being an entire lunation, cast that away, and the remainder 3 shall be that year’s epact; and so on, adding yearly 11 days. To find the epact, having the prime or golden number given, you have this rule: Divide by three; for each one left add ten;Thirty reject: the prime makes epact then.John Harris

   Etymology: ἐπαϰτη.

   As the cycle of the moon seems to shew the epacts, and that of the sun the dominical letter, throughout all their variations; so this Dionysian period serves to shew these two cycles both together, and how they proceed or vary all along, ’till at last they accomplish their period, and both together take their beginning again, after every 532d year. William Holder, on Time.

1. Epact

   The epact (Latin: epactae, from Ancient Greek: ἐπακται ἡμεραι (epaktai hēmerai) = added days), used to be described by medieval computists as the age of a phase of the Moon in days on 22 March; in the newer Gregorian calendar, however, the epact is reckoned as the age of the ecclesiastical moon on 1 January. Its principal use is in determining the date of Easter by computistical methods. It varies (usually by 11 days) from year to year, because of the difference between the solar year of 365–366 days and the lunar year of 354–355 days.
