In our country people are free to make up whatever holiday they wish, and if they can get enough popular support (i.e. Mother's Day) then it becomes legitimate.

It doesn't become a legitimate holiday until the companies producing greeting cards and candy make a substantial profit from it.

Hallmark has made a concerted effort to push "Grandparents' Day," but so far it is seen as a marketing device.
