Mount Vernon is open to visitors throughout the inauguration week.  We look forward to seeing you.


This Bible contains a sheet of paper carefully inscribed with the marriage date of Augustine Washington (ca. 1694-1743) and his second wife, Mary Ball (1708-1789), as well as the birth dates of their six children. George Washington, their eldest child, was born "about 10 in the Morning" on February 11, 1731/32, according to the Julian calendar then in use. When England adopted the Gregorian calendar in 1752 (which we still observe today) this date changed to February 22, 1732 - the day Washington considered to be his birthday.
