Two (Kind of) Useful Old Calendars

Here is a of calendar from yesteryear you can actually use today...

"Clapp's telegraphic calendar. A table for instantly finding the day of the month, and the day of the week, in any year, from the birth of Christ to the year 3200 inclusive. by S. Clapp Jr., Athol. 1850."

And one from Webster's...

"Webster's note and draft calendar for the years 1866, 1867 & 1868."
