Maundy Thursday, or 'Jueves Santo' as it is known in Argentina, is a deeply significant holiday in this South American country. It falls on the Thursday before Easter and marks the day on which Jesus Christ shared the Last Supper with his disciples. In Argentina, a predominantly Catholic country, Maundy Thursday is a public holiday where businesses and schools close so citizens can partake in religious rituals.

On Maundy Thursday, Argentinians commemorate the Agony in the Garden, the betrayal of Christ by Judas, and the institution of the Eucharist. Many attend mass and participate in the Washing of the Feet ceremony, a noteworthy component of the Maundy Thursday service. It represents Jesus' act of humility and service when he washed his disciples' feet.

Due to its religious significance, Maundy Thursday is often a quiet day. Many families will spend the day preparing for the Easter weekend and the main meal will often include fish, in accordance with the Catholic tradition of abstaining from meat on the day. Like many other countries, Maundy Thursday in Argentina is more than a day off; it is a crucial part of the Easter period and an important opportunity for people to reflect on their faith.
