Mother's Day is an annual holiday celebrated in the United States on the second Sunday in May. Mother's Day recognizes mothers, motherhood and maternal bonds in general, as well as their positive contributions to their families and society. It was established by Anna Jarvis, with the first official Mother's Day celebrated through a service of worship at St. Andrew's Methodist Church in Grafton, West Virginia, on May 10, 1908. Popular observances include holiday card and gift giving, churchgoing often accompanied by the distribution of carnations, and family dinners. In the United States, Mother's Day complements similar celebrations honoring family members, such as Father's Day, Siblings Day and Grandparents Day.

In the United States, public holidays are set by federal, state, and local governments and are often observed by closing government offices or giving government employees paid time off. The federal government does not require any private business to close or offer paid time off, as is the case for most state local governments, so employers determine which holidays to observe.
