Maundy Thursday, also known as Holy Thursday, is celebrated in Paraguay as a part of Holy Week proceeding to Easter. The holiday commemorates the Last Supper of Jesus Christ with his Apostles, as described in the Canonical gospels. This event marks the institution of the Eucharist, which is a significant rite in many Christian churches. In Paraguay, as with many Christian nations, the day is observed with religious masses, ceremonies, and processions.

Catholicism being the dominant religion in Paraguay, Maundy Thursday is a significant day in the Paraguayan religious calendar. The religious ceremonies and rites are often accompanied by strong cultural and local tradition. The washing of the feet is one of the key rituals carried out across many Paraguayan Churches, mimicking Jesus's act of washing his disciples' feet during the Last Supper. Also, it's common practice that the Priests and Bishops move through important Biblical stages of Holy Week in a series of Masses.

In terms of public life, Maundy Thursday is regarded as a public holiday in Paraguay, meaning all schools and most businesses are closed. Many people use the day off to spend time with their family and friends and to prepare for the remaining Holy Week events. Despite the solemn nature of the event, there is a festive atmosphere as locals and tourists embrace the holiday's community feel through public processions, communal meals, and quiet reflection, preserving and portraying Paraguay’s rich cultural heritage.
