Argentina celebrates Mother's Day on which Sunday in October?

Argentina celebrates Mother’s Day on the third Sunday in October.

Argentina’s date differs from the second Sunday in May used in the United States and many other countries. The Argentine observance is linked to an older Catholic calendar date, 11 October, associated with the Maternity of the Blessed Virgin Mary.

After the Second Vatican Council moved that Marian celebration to 1 January, Argentina’s Mother’s Day shifted to the third Sunday of October through popular tradition. The Sunday format makes the exact calendar date vary from year to year, but it always falls within October.

Argentina’s timing can cause confusion because October is spring in the Southern Hemisphere, while May is autumn there. The country’s observance is also described as Día de la Madre and is commonly celebrated with family meals, gifts, and gatherings. The third Sunday should not be confused with the third Monday, which some calendars list for other October observances; Argentina’s Mother’s Day itself is Sunday.
