It’s Flag Day, a day that honors the adoption of the United States flag on June 14, 1777. The original resolution declared the flag would have 13 alternating red and white stripes and a blue field with 13 white stars, representing a new constellation — a powerful symbol of unity and independence that continues to fly proudly today.

Americans will celebrate Flag Day on Saturday, marking the anniversary of Congress adopting the design of the U.S. flag. At Allegiance Flag Supply in North Charleston, South Carolina, more than 6,000 flags are sewn weekly.
