Argentina Mother's Day 2026 date and history

In Argentina, Mother's Day is observed annually on the third Sunday of October. For the year 2026, the celebration is scheduled for October 18.

The tradition is rooted in religious history. In 1931, Pope Pius XI dedicated October 11 to the “Divine Motherhood of Mary” to honor the Council of Ephesus. During the administration of José Félix Uriburu, the Argentine government adopted this religious initiative, initially setting the celebration for the Sunday before or after October 11. Over time, the date was standardized to the third Sunday of the month.

Beyond its cultural and emotional significance, the holiday has a substantial impact on the Argentine economy, driving high demand in sectors such as jewelry, flowers, and restaurants.
