What are the similarities and differences in ways Easter is celebrated in the US, Spain and Mexico?

Spain:

Spain is well-renowned for its Semana Santa or Holy Week traditions. A common feature of Easter celebrations in Spain is the ubiquitous use of the nazareno or penitential robe for use in processions, representing the Christian sacrament of penance, or reconciliation with God. While this might seem like a rather sombre way to celebrate the resurrection of Christ, the festival is not without its own fun, celebration and culinary tradition.

Mexico:

Nearly 90% of Mexicans practice Catholicism which means that nearly 100 million Christians have a reason to believe that the Semana Santa, the holy Week leading up to Easter, is the most important holiday in the church calendar. Passionate celebrations can be found all through the country, with different areas celebrating in different ways. On Domingo de Ramos (‘Palm Sunday’), the arrival of Jesus in Jerusalem is commemorated. Many processions reenacting Jesus’ great entry are conducted and woven palms are sold outside churches.

Similarities:

They all celebrate a week about Christian stuff, which they celebrate about Jesus and they create like a carnaval about showing scenes of what they think it happen to Jesus.
