TABLE 829.— PERPETUAL CALENDAR* 



This calendar gives the day of the week for any known date from the beginning of the Christian 

 Era down to the year 2400. 



Dominical letters 



To find the calendar for any year of the Christian Era, first find the Dominical letter for the 

 year in the upper section of the table. Two letters are given for leap years ; the first is to be used 

 for January and February, the second for the other months. In the lower section of the table, 

 find the column in which the Dominical letter for the year is in the same line with the month 

 for which the calendar is desired ; this column gives the days of the week that are to be used with 

 the month. 



E.g., in the table of Dominical Letters >ve find that the letter for 1951 is G; in the line with 

 July, this letter occurs in the first column; hence July 4, 1951, is Wednesday.
