In UK, Ireland and Nigeria Mothering Sunday falls on the 4th Sunday of Lent. A throwback to 16th century tradition of returning to mother church, later the Victorian practice of permitting girls working as domestics to go home and visit their families.

A "Mother's Day" of some sort is practiced in most cultures and recognised officially in many countries. The 2nd of May event which RB denigrated above as an American invention, happens to be celebratred by dozens of cultures and countires. All of which have the same sentiment at heart, which is to honour one's mother.

The two dates are annoying to me, as I have to remember to pick up a Mothering Sunday card in March and then remember to send it in May. Involves too flipping much remembering.
