Flag Day

“In 1893, the Society of Colonial Dames succeeded in getting a resolution passed to have the flag displayed on all of the city’s public buildings. Elizabeth Duane Gillespie, a direct descendant of Benjamin Franklin and the president of the Colonial Dames of Pennsylvania, that same year tried to get the city to call June 14 Flag Day. Resolutions by women were not granted much notice, however, and it was not until May 7, 1937, that Pennsylvania became the first state to establish the June 14 Flag Day as a legal holiday. Flag Day is a nationwide observance today, but Pennsylvania is the only state that recognizes it as a legal holiday.”
