National Doctors' Day is observed in the United States every March 30 to honor physicians for their contributions to healthcare. The holiday originated on March 30, 1933, in Winder, Georgia, when Eudora Brown Almond, the wife of Dr. Charles B. Almond, initiated the observance by sending greeting cards to doctors and placing flowers on the graves of deceased physicians. The red carnation was chosen as the symbolic flower for this day. National Doctors' Day was officially recognized in 1958 when the U.S. House of Representatives adopted a resolution commemorating the occasion, and it was later designated as a national holiday by President George Bush in 1990. Celebrations typically include sending thank-you cards to physicians and laying red carnations on the graves of deceased doctors, as well as visiting doctors' offices with homemade snacks.
