The Council of State says in today's state media that voting for municipal assemblies will take place on October 22.
It doesn't set the date of voting for the country's parliament, which selects the Council of State and the president. Elections are held every five years. Castro has said he'll step down as president in February, although he is expected to remain head of the ruling Communist Party.
Above the municipal level, Cuban elections are choices between candidates preselected by the Cuban Communist Party and related organisations.
