CALENDAR 



For ascertaining any day of the week for any given time within two hundred years from the 

 introduction of the New Style, 1753, to 1952, inclusive. 



Ecclesiastical Calendar. The Church calen- 

 dar is regulated partly by the sun's position 

 and partly by the moon's phases. Such days 

 as Christmas, the Feast of the Circumcision 

 and the Nativity of the Blessed Virgin are 

 fixed days, originally set according to the solar 

 calendar. Such days as Easter, however, are 

 known as movable feasts, their date being 

 determined by the moon's periods. Thus 

 Easter is the first Sunday after the first full 

 moon upon or following the vernal equinox. 

 The other principal movable feasts are Ash 

 Wednesday, Palm Sunday, Good Friday, Ascen- 

 sion and Pentecost. 



Hebrew Calendar. Hebrew chronology be-

 have taken place 3,760 years and 3 months be- 

 fore the beginning of the Christian Era. To 



the number of years in the Gregorian cal- 

 endar, 3,761 must be added to find the number 

 of the Hebrew years ; thus 1917 in the Gregorian 

 calendar is 1917+3761, or 5678. The Hebrew 

 year ordinarily consists of twelve lunar months : 

 Tisri, Hesvan, Kislev, Tebet, Sebat, Adar, 

 Nisan, Yiar, Sivan, Tamuz, Ab and Elul. These 

 months are alternately 30 and 29 days long. 

 At intervals of nineteen years, however, an 

 extra or embolismic month of 29 days, called 

 Veadar, is inserted between Adar and Nisan, 

 and Adar is given 30 days instead of 29, as 

 usual. 



Mohammedan Calendar. The Mohammedans 

 reckon time from the Hegira, which occurred 

 in A. D. 622. The Mohammedan year consists 

 of twelve lunar months, or 354 days. As the 

 calendar year is much shorter than the solar
