CALENDAR. 1751, and after great inconvenience had been experienced for nearly two centuries, from tlie difference of the reckoning, that an act vas passed (24 Geo. II., 1751) for eiiualizing the style in Great Britain and Ireland with that used in other countries of Europe. It was then enacted that 11 days should be omitted after the 2d of September, 1752, so that the ensuing day should be the 14th. A similar change was about the same time made in Sweden and Tus- cany, and Russia is now the only country which adheres to the old style: an adherence which renders it necessary, when a letter is thence ad- dressed to a person in another country, that the June 27 date should be given thus : April Jj or j^. ^ • It will be observed that the years 1800 and 1900, not being considered by us as leap years, have interjected two more days, making the dif- ference thirteen days between old and new style, French Revolutionary Calend.r. The French nation, in 1793, undertook the task of making a new calendar, professedly upon philo- sophical principles. The new era was dated from the minute of the autumnal equinox (Sep- tember 22, 1792), which was also the day from which the existence of the Republic was reck- oned (although the formal jiroclamation of the Republic was on September 21). There were 12 months of 30 days each, divided into decades, in which the days were named numerically — Pri- midi, Duodi, and so on, up to Decadi. The re- maining five days were grouped as festal days at the end of the year, and known as Snnsciilottides. The months, seasons, and festivals were arranged PERPETUAL CALE.NDAR 28 CALENDAR. as follows (the table being for the years I., II., III., v., VI., VII., the dates varying by one or two days in the remaining years) : DAY OF THE MONTH Jan.

A sixth additional day in leap years was named le jour dc la Ift-volutioii. This calendar was a product of the revolt against Christianity, and it existed until the old system was restored by Napoleon, December 31, 1805. See Chronol- ogy. PERrETl'AL Calendar. An arrangement for ascertaining the day of the week correspond- ing to any desired date, and for solving other similar problems. The following form of per-, petual calendar was arranged bj' Capt. J. ller- scliel, and is probably the best yet devised. As here given, it covers the period from 1798 to 1950, but it can be extended easily in either direction. Every date is composed of four elements, viz. : ( 1 ) Day of the week. (2) Day of the month. (3) Name of the month. (4) Number of the year. Anj- three of these ele- ments being given, wc can find the fourth from the perpetual calendar. Thus, supjiose we wish to find what (lay of the week cor- responded to March 4, 1805, on which day Lincoln was inaugurated President of the I'nited States for the second time. Entering the calendar in the column headed 'March,' and opposite the 'day of the month' 4, we find the sign -f. Now, en- tering the column contain- ing the year I8G5, and go- ing up it to the same sign + , we find opposite that sign, on the right, the 'day of the week' Saturday. Ac- ciinlingly. Lincoln was in- augurated on a Saturday. .gain. suppose it is re- quired to find in what years
