Mother’s Day is celebrated on the second Sunday in May. On this occasion, mother usually receives greeting cards and gifts from her husband and children.  For most mothers, the rarest and best gift is a day of rest. Often, families honor mother by taking her out for dinner. In some households the husband and children take over meal preparations so that mom can spend a whole day away from the kitchen. Serving her breakfast in bed is another family ritual. Later in the day, parents may take their children to visit their grandparents.
    Flowers are an important part of the holiday. Mothers are often given corsages for the occasion, particularly if they are elderly.
    The idea of setting aside a special day to honor mothers did not originate in the United States. In England, Mothering Sunday, celebrated during Lent, was once traditional. The Yugoslavs and many other people have long observed a holiday for mothers. In the United States, Mother’s Day has been a national tradition since 1915.
