Mother's Day comes on the second Sunday in May. It is a day when Americans honour their mothers. It is not a national holiday. Mother's Day is an American national observance in honour of motherhood. The holiday, suggested by Anna Jarvis of Philadelphia, was set (1914) by an act of Congress for annual celebration. It is also observed in England and Germany. In 1907, the day was celebrated in a church in Philadelphia, Pennsylvania. A member of that church planned the Sunday morning service to honour her own mother. More and more churches in cities and states set aside the day to honour mothers. Since 1914, the whole country has observed Mother's day. Most mothers like to celebrate the day with family reunions. Many people send their mothers a card or a gift. Some people take their mothers to a restaurant for dinner. It is a custom to wear a red or pink flower if one's mother is living. It is the custom to wear a white flower if one's mother is dead.
