For Leap Year be sure and Sub one for Jan. and Feb., but, not for the other months. Years divided by 4 with no remainder are leap years, except the year 1900.

The 20th. Century began 1901, not 1900.

Add 5 to the day of the month required and to this amount add the number that stands at the head of the column which contains the desired year, also the number at the head of the column which contains the desired month. Divide the sum total by 7 and the remainder will be the figure at the the head of the column, beneath which is the day of the week. When there is no remainder the day of the week will be on Sunday.

Example: - Upon what day of the week did July 4 1821, fall.

Day of month.................................................. 4.

Add 5 to day of month [if in 19th. Century] thus.................. 5

(20th. Century add 3 Instead of 5 ) Add figure at head of column in which the year number is.

For year 1822 it is........................8.

Add figure that stands above the required month. For July, it is....3:

Total 18.

Divide the total by 7. and the remainder will give a figure that stands at the head of the column beneath which you will find the day of the week, as follows: 7 into 18 goes 2 times and 4 remainder. Look at bottom of column, marked "4", and you find "Thur". Hence, July 4, falls on Thursday in 1821. Find your own week-day of birth, or any other, In same way, except it happen in Jan., or Feb., as above stated. For 18th. Century, [If you need go back so far] It is not necessary to add the 5 or 3, but make sum in same way otherwise. This is the simplest Ready Reference Calender ever given. Jan., 4, Feb., 1 Mar., 1, Apr., 5, May 3, June 7, July 5, Aug., 2, Sep., 6, Oct., 4, Nov. 1, and Dec, 6, always in the same year, fall on the same day of the week.
