It wasn't until 1910 that the first Mother's Day was proclaimed in the U.S. By the following year, however, each state had created its own observances, as had various nations around the world. American President Woodrow Wilson declared Mother's Day an official national holiday in 1914. Nowadays, on the second Sunday of every May, people everywhere buy flowers, give chocolates, and send cards to the women who have raised them with love, courage, and devotion.
