There are traditionally 40 days in Lent; these are marked by fasting, both from foods and festivities, and by other acts of penance. The three traditional practices to be taken up with renewed vigour during Lent are prayer (justice towards God), fasting (justice towards self), and almsgiving (justice towards neighbours).

Some of the most famous are the Carnival of Barranquilla, the Carnival of Santa Cruz de Tenerife, the Carnival of Venice, Cologne Carnival, the New Orleans Mardi Gras, the Rio Carnaval, and the Trinidad and Tobago Carnival. The day immediately preceding Lent is called Mardi Gras ("Fat Tuesday")
