CHRONOLOGY.
711
The lid. table shews the golden number for 4000 years afterthe birth of Christ, by looking for the even hundreds of any givenyear at the left hand, and for the rest to make up that year at the headof the Table ; and where the columns meet, you have the goldennumber for the given year. Thus, suppose the golden numberwas wanted for the year 18 IQ, look for 1800 at the left hand of thetable, and for 10 at the top of it ; then guiding your eye down-ward from 10 to the angle over against 1800, you will find 0, whichis the golden number for the present year. But as the lunar cycle
of 19 years sometimes includes five leap-years, and at other timeonly four, this table will sometimes vary a day from the truth inleap-years after February. And it is impossible to har e one morecorrect, unless we extend it to four times 19 or 76 years ; in whichthere are 19 leap-years without a remainder. But even then tohave it of perpetual use, it must be adapted to the old style ; be-cause, in every centurial year not divisible by four, the regular,course of leap-years is interrupted in the new.

IV. The cycle of Easter, or tlie Dionysian period, is a revolu-tion of 532 years, found by multiplying the solar cycle 28, by (helunar cycle 19. It the new moons did not anticipate upon thiscycle, Easter day would always be the Sunday next after the firstfull moon wki'h iollows the 21sl of March. But, on account ofthe above anticipation, to which no proper regard was paid beforethe alteration of the style, the ecclesiastical Easter has severaltimes been a week different from the true Easter within tiiis lustcentury: which inconvenience is now remedied by making thetable, which used to find Easter for ever, in the Common PrayerBook, of no longer use than the lunar diti'orcr.«-e from the newstvle will admit of. The earliest Easter possible is the 22d of-March, the latest the 25th of April. Withm these limits are 35days, and the number belonging to each of them is called thenumber of direc tion ; because thereby the time of Easter is foundfor any given year. The first-seven letters of the alphabet arecommonly placed in the annual almanackto sitew on what daysof the week the days of the m'onths fail throughout the year.One of those letters' against Sunday, is printed in a capitalform, and called the dominical letter; the other six are in-serted in small characters, to-denote the other six days of theweek. As a common Julian year contains 365 days, if this num-ber be divided by seven there will remain one day, whence the
year begins and ends on the same day of the week ; and thereforethe next year will begin on the day following. Hence, when-Jan.begins on Sunday, A is the dominical letter for that vear : Then,because the next year begins on Monday, the Sunday will foil on'the 7th day, to which is annexed the seventh letter G, whichtherefore will be the dominical letter for that year; and as the third'year will begin on Tuesday, the Sunday will'fail on the sixth day;therefore F will he the dominical letter for that year. IV hence itis evident, that the dominical letters will go annually in a retrogradeorder thus, G, F, E, j), C, B, A. And, in tire course of sevenyears, if they were all common ones, the same days of the week anddominical letters would return, to the same, days of the months.But because there are 366 days in a leap-year, it this number be .divided bv seven, there will remain two days over and above the52 weeks, of which the year consists. And therefore, if the leap-year begins on Sunday, it will end on Monday; and the nextyear will begin on Tuesday, the first Sunday whereof must fall onthe Glh of January, to which is annexed the letter F, and not G,as in common years. From the leap-year thin returning everyfourth year, the order of the dominical letters is interrupted; andthe series cannot return to its first state till after four times sevenor 28 years; and then the same days of the months return in order-,to the’saiue.days of the week as. before,.
