Two letters are given for leap years; the first is to be used with 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 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. For example, in the table of Dominical letters the letter for 1962 is G; in the line with July, this letter occurs in the first column; hence July 4, 1962, is Wednesday. *After Smithsonian Physical Tables, 9th ed., Washington, DC., 1954. †A.D 1 through A.D. 4 only. ‡A.D. 5 through AD 99 only. §On and after 1582, October 15 only. ¶ On and before 1582, October 4 only.
