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.
Mother's Day is on Sunday, May 9, 2027, which is 330 days away. The live countdown above ticks down to the exact moment, to the second.
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.
