According to the official calendar, the 2012 carnival will take place between 17 and 21 February.
- The Rio de Janeiro escolas de samba will parade at the sambadrome on Sunday 19 and Monday 20.
- The São Paulo parades will take place on Friday 17 and Saturday 18.
Although the dates seem miles away, the farsighted travellers will make accommodation arrangements for the period long in advance – it is the only way of finding good value accommodation for places like Rio or Salvador.
As more details emerge I will keep you posted.
