Here in the UK, Mother's Day was in March. It's always before Easter. During the Covid lockdowns, one very well-known store mentioned in its e-mails that they were sorry if they offended anyone who had recently experienced illness/loss. It didn't appear this year. Adverts for chocolate didn't mention the day specifically.
Its origin is more interesting. Historically called Mothering Sunday, it was the day when staff (servants) were allowed time off to visit their mothers.
My mother chooses to go to my brother on that day. Not going to argue with her, I just welcome the opportunity to do what I want. She gets gift and card the day before, often with a cream cake!
