. . . . The Story of Ben's Birthdate . . . .

Benjamin Franklin was born in Boston on the day known in the English-speaking world as January 6. His birth is recorded in the City Registry of Boston, Boston Birth records, at vol. 5, page 113, and also in the baptismal records of the Clerk of the Old South Church in Boston. In 1752, however, Great Britain, after literally centuries of obstinate refusal, finally agreed to move from the Julian to the Gregorian calendar. The Gregorian calendar resolved virtually all the shortcomings of the older Julian and is still the calendar system we use today.

"So Benjamin Franklin's birthday, under the New Style calendar, is January 17. But it seems Franklin was unable to relinquish January 6. He used that date, for example, in his own epitaph."

The New Style calendar, as it came to be called, required the adding of eleven days in order to bring the heretofore Julian users into conformance with the Gregorian. Britain's colonies followed its lead. So Benjamin Franklin's birthday, under the New Style calendar, is January 17. But it seems Franklin was unable to relinquish January 6. He used that date, for example, in his own epitaph. Historians, though, commonly make the eleven day adjustment and use January 17. The authoritative Dictionary of American Biography, for example, uses January 17, 1706. The birthdays of most of the founders of the United States of America -- perhaps most publicly, George Washington's -- are caught in the same time warp. The proper way to render the date, both ways, is: January 6, 1706 (O.S.) and January 17, 1706 (N.S.)

Here's Ben's epitaph: "The Body of B. Franklin, Printer; Like the Cover of an old Book, Its Contents torn out, And stript of its Lettering and Gilding, Lies here, Food for Worms. But the Work shall not be wholly lost: For it will, as he believ'd, appear once more, In a new & more perfect Edition, Corrected and amended By the Author. He was born Jan. 6. 1706. Died _____ 17__
