Various observances honoring mothers existed in America during the 1870s and the 1880s, but these never had resonance beyond the local level.

The modern holiday of Mother’s Day was first celebrated in 1908, when
Anna Jarvis held a memorial for her mother. She then began a campaign to make “Mother’s Day” a recognized holiday in the United States. Although she was successful in 1914, she was already disappointed with its commercialization by the 1920s. Jarvis’ holiday was adopted by other countries and it is now celebrated all over the world. – Wikipedia

qualified her to create a holiday?

I ask these questions to encourage you,
for Anna had no qualifications beyond her love and her commitment.
You have these both of these attributes, don’t you?
