Mother's Day is a celebration that honors mothers and 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 March, April, or May. It complements Father's Day, a celebration honoring fathers.
Celebrations of mothers and motherhood occur throughout the world. Many of these trace back to ancient festivals, like the Greek cult to Cybele, the Roman festival of Hilaria, or the Christian Mothering Sunday celebration. However, the modern holiday is an American invention and not directly descended from these celebrations. Despite this, in some countries Mother's Day has become synonymous with these older traditions.
In the United States, Mother's Day is an annual holiday celebrated on the second Sunday in May.-[via Wikipedia (1), (2)].
