Description
column will be 2, which indicates the day i of the week upon which the first day of January 1917 falls. In a like manner the January column is continued as far as is desired. In this same manner the Februaryl month column is built up. The lMarch month column for 1915 contains the nnmeral 2, indicating that the first day of March 1915 fell-on the second day of the week. Since 1916 is a leap year, one numeral in the regular consecutive order of numerals is dropped between 1915 and 1916, which makes the next numeral in said March month column numeral mi. According to the above rule the next numeral in the March month column will be numeral 1, and so on until the column has been continued as far as desired. In the same manner the remaining nine month columns are built up.
If it is desired to ascertain a diierent day of the month than the lirst day, this is done by first determining' the first day oi the month in which the desired date falls. Then upon consulting the corresponding month calendar, the day of the week of the desired date will be found. As an instance of this, suppose it is desired to lmow the day of the week upon which the Fourth of July will be in 1920. ,The index is consulted in the 1920 year line, and in the Jul column we find the numeral 5, which indicates that the first day of July 1920-.will be on Thursday, the fifth day of the week. Then upon consultin month calendar 5 we find the Fourt of July will be on Sunday. In this same manner the day of the week of any other desired date may be ascertained.
VThe index shown in the drawin extends from years 1880 to 1930 inclusive, but it willbe apparent from the above that this index may be extended in either direction as far as desired, or the index may be shortened to indicate only one or more years, as may be desired.
While I have illustrated `and described the preferred form of my invention, I do not desire toI be limited to the precise details set forth, l.1-1t'desire to avail myself of such variations and changes'as come within the scope of the appended claims.

A calendar comprising thirteen par allel columns, one of the columns being a column of year y dates arranged consecutively with the leap years displayed 1n a distinctive manner and the other twelve col umns being month columns designated January toDecemher month columns respectively and each bein made up of seven recurringfsymbols which have a consecutive relation with each other and relate to the days' of the week, said symbols being arranged in consecutive order in each month columnexcept in the January and February month columns Where one symbol is dropped from the consecutive order between each leap year and the year following such leap year and in each of the other ten month columns one symbol is dropped from the regular consecutive order between each leap year and the year previous to such leap year.
2. A calendar comprising seven month calendars each beginning on a different day of the week and having a designating symbol, said designating symbols having a consecutive orderly relation corresponding to the days of the week upon which the first days of the month calendars begin; and an index having a column of consecutive year dates with the leap years displayedin a distinctive manner and twelve month columns parallel with the year dates column and designated as January to December month columns respectively, each of the month columns being made up Vof symbols corresponding to the designating symbols of the month calendars and arranged in a consecutive order except in the January and February month columns where one symbol is dropped from the consecutive order between each leap year and the fyear following such leap year and in eacho the other ten month columns one symbolV is dropped from the regular consecutive order between each leap year and the year preceding such leap year.
