The following are the national public holidays and other observances of Argentina.

Though holidays of many faiths are respected, public holidays usually include most Catholic based holidays. Historic holidays include the celebration of the May Revolution (25 May), Independence Day (9 July), National Flag Day (20 June) and the death of José de San Martín (17 August).

The extended family gathers on Christmas Eve at around 9 p.m. for dinner, music, and often dancing. Candies are served just before midnight, when the fireworks begin. They also open gifts from Papá Noel (Father Christmas or "Santa Claus"). New Year's Day is also marked with fireworks. Other widely observed holidays include Good Friday, Easter, Labor Day (1 May) and Veterans Day (formerly Malvinas Day, 2 April).

The "movable holidays" whose dates coincide with Tuesdays and Wednesdays will be moved to the previous Monday. Those that coincide with Thursday, Friday, Saturday and Sunday will be moved to the following Monday. Every employee is entitled to 15 paid public holidays and every year the government adds a few more holidays known as "bridge holidays" which means that a holiday lasts two days.^{[citation needed]}
