Mothers are celebrated in many countries on different dates and in different ways. While the customs and traditions vary, everyone knows how important it is to honor moms for everything they do all year long.
In Japan
Mother's Day is celebrated on the second Sunday in May and is symbolized by beautiful carnations -- which represent the gentle strength of mothers who are revered in Japanese culture.
"Children draw pictures of their mothers in school and sometimes enter them in art contests," says Gross-Loh. "Like most other countries, Mother's Day is a day of pampering for moms -- kids help take over the household chores, have a special family meal, like sushi or eggs, and give their mothers red carnations or roses and cards."

In United Kingdom
In the UK, Mother's Day is celebrated on the fourth Sunday of Lent, and is called Mothering Sunday. During medieval times, poor families often sent their children off to work as domestic servants or apprentices to rich families. Their rare day off was traditionally granted during the Lenten season, so they could worship the Virgin Mary and visit their home, "mother church" and their families. The children would often pick flowers to give to their mothers and bake special cakes called Mothering Cakes or Simnel Cakes (the holiday even used to be known as Refreshment Sunday because the strict Lent fasting rules were put aside for the holiday). Today, Mother's Day in the UK is celebrated in the same way as it is in America, with flowers, cards, gifts and family meals.

In India
In culturally diverse India, a westernized version of Mother's Day is celebrated on the second Sunday in May, when Indians reflect upon the importance of mothers in their lives and the sacrifices they have made.

However, Hindus in India celebrate the goddess Durga, or Divine Mother, during a 10-day festival called Durga Puja in October. Durga Puja celebrates the triumph of good over evil and is earmarked by gifts given to friends and family, as well as feasts and celebrations.

In Ethiopia
Mother's Day is celebrated at the end of the fall rainy season, as part of the three-day Antrosht festival, dedicated to moms. When the weather clears up and the skies empty of rain, family members come home to celebrate with a large feast. Daughters traditionally bring vegetables, butter, spices and cheese, while the sons bring meat of various types, including lamb or bull. These will be included in a traditional hash recipe. Singing and dancing is shared by all family members.

In Yugoslavia
Another country which needs three days to fully acknowledge their mothers and the spirit of family is Yugoslavia, where Mother's Day takes place in December and is part of a series of holidays including Children's Day and Father's Day. All three holidays take place on consecutive Sundays and require lots of rope!

On Children's Day, children are tied up and must agree to behave before they are unbound. On Mother's Day, it is the mom's turn to be tied up, where she will remain until she supplies yummy treats and small gifts to her children. Finally it is father's turn. The dads are tied up with rope until they give their families Christmas gifts. At that point, everybody feasts.

In Spain
Unlike the United States and several other countries, Mother’s Day in Spain is celebrated on December 8. Spaniards pay tribute not only to their own mothers on this day, but also to the Virgin Mary. Mother’s Day in Spain includes religious celebrations across the country.

In USA

Arab world
other's Day in most Arab countries is celebrated on 21 March, the first day of spring in the northern hemisphere. It was introduced in Egypt by journalist Mustafa Amin , in his book Smiling America (1943). The idea was overlooked at the time. Later Amin heard the story of a widowed mother who devoted her whole life to raising her son until he became a doctor. The son then married and left without showing any gratitude to his mother. Hearing this, Amin became motivated to promote "Mother's Day". The idea was first ridiculed by president Gamal Abdel Nasser[citation needed] but he eventually accepted it and Mother's Day was first celebrated on 21 March 1956[citation needed]. The practice has since been copied by other Arab countries.
When Mustafa Amin was arrested and imprisoned, there were attempts to change the name of the holiday from "Mother's Day" to "Family Day" as the government wished to prevent the occasion from reminding people of its founder[citation needed]. These attempts were unsuccessful and celebrations continued to be held on that day; classic songs celebrating mothers remain famous to this day.
