The holiday traditionally falls on the third Sunday of October. This year it lands on October 18, a date that brings family celebrations as well as a seasonal boost for retailers.
Argentina will celebrate Mother’s Day on Sunday, October 18, in 2026. The date is set by the calendar because the holiday falls on the third Sunday of October.
The tradition dates to 1931, when Pope Pius XI dedicated October 11 to the Divine Maternity of Mary. Argentina’s government then set Mother’s Day for the Sunday before or after that date. The country later fixed the celebration on the third Sunday of October.
The holiday is also a significant retail occasion. Demand for flowers, jewellery and restaurant bookings typically rises in the days beforehand. Dates vary internationally: many countries celebrate in May, while several Arab countries mark Mother’s Day on March 21.
