This is what I came across.
The Story of Mother's Day
The earliest Mother's Day celebrations can be traced back to the spring
celebrations of ancient Greece in honour of Rhea, the Mother of the
Gods. During the 1600's England celebrated a day called "Mothering
Sunday". Celebrated on the 4th Sunday of Lent the 40 day period
leading up to Easter). "Mothering Sunday" honoured the mothers
During this time many of England's poor worked as servants for the
wealthy. As most jobs were located far from their homes, the servants
would live at the houses of their employers. On Mothering Sunday the
servants would have the day off and were encouraged to return home and
spend the day with their mothers. A special cake, called the mothering
cake, was often brought along to provide a festive touch.
As Christianity spread throughout Europe the celebration changed to
honour the "Mother Church" - the spiritual power that gave
them life and protected them from harm. Over time the church festival
blended with the Mothering Sunday celebration. People began honouring
their mothers as well as the church.
In the United States Mother's Day was first suggested in 1872 by Julia
Ward Howe (who wrote the words to the Battle Hymn of the Republic) as a
day dedicated to peace.
Ms. Howe would hold organized Mother's Day meetings in Boston, Mass
In 1907 Ana Jarvis, from Philadelphia, began a campaign to establish a
national Mother's Day. Ms Jaris persuaded her mother's church in
Grafton, West Virginia to celebrate Mother's Day on the second
anniversary of her mother's death, the 2nd Sunday of May. By the next
year Mother's Day was also celebrated in Philadelphia.
Ms. Jarvis and her supporters began to write to ministers, businessmen,
and politicians in their quest to establish a national Mother's Day. It
was successful as by 1911 Mother's Day was celebrated in almost every
state. President Woodrow Wilson, in 1914, made the official announcement
proclaiming Mother's Day as a national holiday that was to be held each
year on the 2nd Sunday of May.
While many countries of the world celebrate their own Mother's Day at
different times throughout the year, there are some countries such as
Denmark, Finland, Italy, Turkey, Australia, and Belgium which also
celebrate Mother's Day on the second Sunday of May. (And that list
should have included Canada).
