Mother’s Day is a celebration honoring the mother of the family or individual, as well as motherhood, maternal bonds, and the influence of mothers in society. It is celebrated on different days in many parts of the world, most commonly in the months of March or May. It complements similar celebrations, largely pushed by commercial interests, honoring family members, such as Father’s Day, Siblings Day, and Grandparents Day. While some countries have a multi-century history of a day to celebrate mothers, the modern American version of holiday began in the United States at the initiative of Anna Jarvis in the early 20th century who organized the first Mother’s Day service of worship and celebration at Andrews Methodist Episcopal Church in Grafton, West Virginia, which serves as the International Mother’s Day Shrine today. It 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, the mother deity Rhea, the Roman festival of Hilaria, or the other Christian ecclesiastical Mothering Sunday celebration (associated with the image of Mother Church). However, in some countries, Mother’s Day is still synonymous with these older traditions.
