Mothering Sunday is the name given in England to the 4th Sunday of lent, when apprentices in former days were given the opportunity to visit their mothers, taking a small present. English children in the 1960's were generally encouraged by schools and churches to observe the same custom.
Mother's Day in the USA is on the second Sunday of May. This was established by a Congress resolution in 1913. On that day Americans are encouraged, not least by shopkeepers, to give presents to their mothers.
