Reformation Day is a religious holiday celebrated on October 31, alongside All Hallows' Eve, in remembrance
of the Reformation. It is celebrated among various Protestants, especially by Lutheran and Reformed church
communities.
It is a civic holiday in the German states of Brandenburg, Mecklenburg-Vorpommern, Saxony, Saxony-Anhalt and
Thuringia. Slovenia celebrates it as well due to the profound contribution of the Reformation to that nation's
cultural development, although Slovenes are mainly Roman Catholics. With the increasing influence of
Protestantism in Latin America (particularly newer groups such as various Evangelical Protestants, Pentecostals
or Charismatics), it has been declared a national holiday in Chile in 2009.
