Mother's Day is a celebration honoring the mother of the family, as well as motherhood, maternal bonds, and the influence of mothers in society. It is celebrated on various days in many parts of the world, most commonly in the months of March or May. It complements similar celebrations honoring family members, such as Father's Day, Siblings Day, and Grandparents Day.
The modern Mother's Day began in the United States, at the initiative of Anna Jarvis in the early 20th century. This is not (directly) related to the many traditional celebrations of mothers and motherhood that have existed throughout the world over thousands of years, such as the Greek cult to Cybele, Rhea the Great Mother of the Gods, the Roman festival of Hilaria, or the Christian Mothering Sunday celebration (originally a commemoration of Mother Church, not motherhood). However, in some countries, Mother's Day is still synonymous with these older traditions.
The U.S.-derived modern version of Mother's Day has been criticized for having become too commercialized. Founder Jarvis herself regretted this commercialism and expressed views on how that was never her intention.
