There is a difference between Mothering Sunday and Mother’s Day.
Firstly, Mothering Sunday is celebrated in the UK and Mother’s Day everywhere else in the world.
Secondly, Mothering Sunday is celebrated on the fourth Sunday in Lent and Mother’s Day is on the first Sunday in May.
Thirdly, traditional Mothering Sunday is when people return to their mother church but then it turned to when those in service (household workers) are given a day off to visit their mothers and they will pick flowers (traditionally daffodils) on their way to their mothers’; Mother’s Day was started by a an American Lady to honour her mother.
So, today is Mothering Sunday in the UK which is nowadays treated the same as Mother’s Day… but it’s not.
