Mother’s Day is a celebration honoring mothers and motherhood, maternal bonds, and the influence of mothers in society. It is celebrated on the second Sunday of May in the United States. It complements Father’s Day, a similar celebration honoring fathers.
The celebration of Mother’s Day began in the United States in the early 20th century; it is not related to the many celebrations of mothers and motherhood that have occurred throughout the world over thousands of years, such as the Greek cult to Cybele, the Roman festival of Hilaria, or the Christian Mothering Sunday celebration. Despite this, in some countries Mother’s Day has become synonymous with these older traditions.
