Mother's Day is a festival derived from the custom of mother-worship in ancient Greece. Formal mother-worship, with ceremonies to Rhea, "the Great Mother of the Gods," were performed on the Ides of March throughout Asia Minor.
In the United States, Mother's Day was given official recognition by Congress on May 9, 1914, after efforts by Miss Anna Jarvis of Philadelphia, Pennsylvania. The second Sunday in May was adopted as the national day "for public expression of love and reverence for the mothers." The national holiday is "dedicated to the memory of the best mother in the world, your mother” The carnation, signifying sweetness, purity and endurance, was adopted as the floral emblem. -The Encyclopedia Britanica
To continue the custom begun in Greece, the Paleothodoros Brother's proudly opened Mother's Day in hopes that the holiday and what it stands for would be cherished every day of the year.
