Mother's Day is celebrated in many parts of the world as a day to honor mothers and motherhood. In the United States, Canada, and Australia it is celebrated on the 2nd Sunday in May.
One indicator of the importance of Mother’s Day is that it’s the busiest day of the year for phone calls, with an estimated 122 million phone calls made in the U.S. alone. There’s a natural desire in most people to want to honor their mother, if it’s possible. That’s why billions of dollars are spent on buying flowers, cards, and taking Mom out to dinner.
