Whence, the EpaBs are either Annual or Menfrual.
Menfrual Epacts, are the Exceffes of the Civil, or Calendar Month, above the Lunar Month. See Month.
Suppofe, e. gr. it were New Moon on the firft Day of January: Since the Lunar Month is 29 Days I2 h 44' 3"; and the Month of January contains 31 Days : The Men- flrual EpaB is 1 Day n h 15' 57".
It muft be obferved, that as the Cycle of 19 Years, anticipates the new Moons by one Day in 5-12 Years ; the fame Cycle of EpaCls will not always hold : The Moon's Anticipation lefTcning the feveral EpaBs by one, every 312 Years.
To have the EpaBs, therefore, point out the New Moons perpetually ; that EpaB given in the Calendar is not fuf- ficient ; but all the 30 EpaBs fhould be bcftowed through-
Annual Epacts, are the Exceffes of the Solar Year out the whole Year, that the Calendar may exhibit all
above the Lunar. See Year.
Hence, as the Julian Year is 355 Days 6 Hours, and the Julian Lunar Year 354 Days 8 h 48' 38" 5 the' an- nual EpaB will be 10 Days 12" n' 22"; that is, nearly, 11 Days. Confequently, the EpaB of 2 Years, is 22 Days; of 3 Years, 33 Days; or rather 3, fince 30 Days make an Embolifmic, or Intercalary Month. See Embolismic.

And, again, that as in 300 Gregorian Years, there is one Biffcxtile Year dropp'd ; the New Moons are thus thrown on the following Day. Confequently, by the Moon's poft-pofition there is one added to every EpaB. See Gregorian.

Again, as the New Moons arc the fame, that is, fall on the fame Day every 19 Years, fo the Difference be- tween the Lunar and Solar Year, is the fame every 19 Years. And becaufe the faid Difference is always to be added to the Lunar Year, in Order to adjuft, or make it equal ro the Solar Year ; hence the faid Difference re- fpecfirely belonging to each Year of the Moon's Cycle, is called the EpaB of the faid Tear, that is, the Number to be added to the faid Year to make it equal to the Solar Year ; The Word being form'd from the Greek, imja, induce, intercalo.
Upon this mutual Refpect, between the Cycle of the Moon, and the Cycle of the EpaBs, is founded this Rule for finding the EpaB belonging to any Year of the Moon's Cycle. Multiply the Year given of the Moon's Cycle into 11 ; if the Product be lefs than 30, it is the EpaB fought ; if the Product be greater than 30, divide it by 30, and the Remainder of the Dividend is the EpaB : For In- llance, I would know the EpaB for the Year 1712, which is the third Year of the Moon's Cycle. Wherefore 3 is the EpaB for 171s : For 11 x 3 = 33, and 33 being di- vided by 30, there is left 3 of the Dividend for the EpaB. See Cycle.
By Help of the EpaB may be found what Day of any Month in any Year the New Moon falls on, thus : To the Number of the Month, from March inclufively, add the EpaB of the Year given ; if the Sum be lefs than 30, fubftract it out of 30 ; if greater, fubftract it out of 60 ; and the Remainder will be the Day, whereon the New Moon will fall.
