days of the month, and the dominical let
tiers return to the same order again.
The Lunar Cycle Cor golden number, or
Metonic cycle, from Melton its inventory
is a period Of 10 years, in which the con-
functions, appositions, and other aspects Of
the moon fall upon the same day Of the
month and within an hour and half Of
the same time. The Roman indictlon Is
a period Of Is years established by Con-
stantine, A. d. 3l2, with reference to the
payment Of certain sums Of money by the
tributaries of Rome. The Julian Period
is the product of these three cycles, multi
piled into each other. 1t is period,
therefore, of 1880 years, and commenced
TO years before the creation, this being
the nearest point at which all three would
begin together That is, the first year Of the
world was the 10th of the Julian Period.
To find the Julian Period, then, for
any year, add together these three quanti-
ties, viz, the year, 4OOl, and 7O9.
At the birth of our Savior, the Solar
Cycle was 8, and the Lunar Cycle l. To
find the Solar Cycle for any year, add 9 to
the year, and divide the sum BY 2s; the
remainder is the solar cycle. If there is
no remainder, the cycle is %.
To find the Lunar Cycle for any year,
add l to the year, aud divide the sum
by 10: the remainder if any is the cycle ;
if none the cycle is 10.
The rule for the Indiction is evident
from what has been said.
Epacs is the moons age at the CON-
mencement of the year.
The movable feasts Of the Romish church
are dependent upon the times of the moon 5
phases and the time Of Easter, which al
ways happens on the FIRST Sunday af-
ter the first full moon after the 2lst
of March. If full moon happen upon
the 2lss Of March, and that day be Sun
day, the following Sunday will be Easter.
AS a common year consists OF % weeks
and l day, it is evident that 1t will always
begin and end upon the same day Of the
week and that the following year will be-
gin upon the mex; day of the week. But,
as Leap Year contains one day more, this
order is destroyed, and the year following
leap year begins two days later i'll TIE
week than the Leap Year did.
The first seven letters Of the alphabet
are used to show upon what day of the
year the first Sunday in the year will fall,
and they are therefore called Dominical
or Sunday letters. Thus, if year COM
mence ON Sunday, and be a common year,
its dominieal letter will be it. The next
year will, as We have seen, begin on Mon
day and the first Sunday viii therefore be
+h. tn dav of ti.e ) Cor, aux fi1c ''9ninieal
letter for this year will be the seventh
letter, or G. The next year will have the
first Sunday on the sixth and its Domini-
cal letter will be T, and so on, in reverse
order. Every Leap Year has two Domin-
ical letters, the first taken in the reverse
order Of the alphabet, marking the Sun
day, until the end Of February, and the
other from that time until the close of the
year.
The following tables will serve as an
Almanac for any length of time by ad-
ding centuries in the same order as those
given, and will show upon what day of
the week and day Of any month in any
given year will fall.
