The custom of setting aside a day to honor mothers can be traced all the way back to the days of Ancient Greece. In Victorian England, "Mothering Day" gave servants a day to go home and spend with their families.

Today, people in different countries honor their mothers on different days. Since 1914, the second Sunday of May has been observed as Mother's Day in the U.S.
