Legalization of "Mother's Day"

After the death of his mother in 1905, Jarvis decided to write to teachers, religious, politicians, lawyers and other personalities to support it in its project to celebrate Mother's Day, the anniversary of the death of his own progenitor, the second Sunday of May.
He had many answers, and in 1910 this date was already held in most of the United States.
In 1914, President Woodrow Wilson signed the proclamation of Mother's Day as a national holiday, which was to be held the second Sunday of May.
The first official celebration took place one day on May 10, so this day was adopted by many other countries as the date of "Mother's Day".
