Mother’s Day is a holiday honoring motherhood that is observed in different forms throughout the world. In the United States, Mother’s Day 2021 will occur on Sunday, May 9. The American incarnation of Mother’s Day was created by Anna Jarvis in 1908 and became an official U.S. holiday in 1914. Jarvis would later denounce the holiday’s commercialization and spent the latter part of her life trying to remove it from the calendar. While dates and celebrations vary, Mother’s Day traditionally involves presenting moms with flowers, cards and other gifts.
