The Venezuela presidential election will be held on April 14, the country's election commission told Reuters.
Acting President Nicolas Maduro, the protege of deceased leader Hugo Chavez, is the favourite to win the election in a likely face-off with centrist opposition Governor Henrique Capriles.
More than 20 world leaders are expected to attend the funeral today, but there will be no burial as he will be embalmed.
Thousands flocked to the streets of Caracas to see the coffin of Chavez travel through the city to lie in state until Friday's funeral.
