Mother's Day in the United States falls on the second Sunday of May. This countdown automatically targets the next one — no date math required.
Anna Jarvis held the first Mother's Day service in Grafton, West Virginia, in 1908 to honor her own mother, and campaigned until President Wilson made it a national observance in 1914.
Jarvis later spent decades fighting the holiday's commercialization — she wanted handwritten letters, not printed cards. The flowers won, but the sentiment endures.
