In the United States Mothers' Day is a major holiday that is celebrated on second Sunday in May.

It is the time when children honor their mothers, grandmothers with cards, gifts, and flowers.

First observed in Philadelphia, Pa. in 1907, it is based on suggestion by Ms Julia Ward Howe in 1872 and Ms Anna Jarvis in 1907. Although it wasn't celebrated in the United Status until 1908, there were special days honoring moms even in the early days of ancient Greece. In those days, however, it was that Rhea, the Mother of the ancient gods that were given honor. Later, in the 1600's, in England there was an annual observance called "The Mothering Sunday." It was celebrated during Lent, on the fourth Sunday. On The Mothering Sunday, the servants, who generally lived with their employers, were encouraged to return home and honor their mothers. It was traditional for them to bring a special cake along to celebrate the occasion. In the U.S., in 1908 Ms Ana Jarvis, from Grafton, W Virginia, began a campaign to establish a national Mother's Day. Jarvis persuaded her mother's church in Grafton, W Virginia to celebrate Mother's Day on the anniversary of her mother's death. A memorial service was held there on May 10, 1908 and in Philadelphia the following year where Mrs. Jarvis moved. Ms. Jarvis and others began a letter-writing campaign to local ministers, businessmen, and politicians in their quest to establish a national Mother's Day. They were successful. President Woodrow Wilson, in 1914, made the official announcement proclaiming Mother's Day a national observance that was to be held each year on the 2nd Sunday of May. Many other countries of the world celebrate their own Mother's Day at different times throughout the year. Denmark, Finland, Italy, Turkey, Australia, and Belgium celebrate Mother's Day on the second Sunday in May, as in the United States.

For florist Mother’s Day is the largest floral holiday of the year.
