The Olympics Games start with the Opening Ceremony at the Olympic Stadium in London on the evening of Friday 27 July. It then runs until Sunday 12 August.
There is a short break, before the Paralympic Games starts on 29 August and runs until 9 September.
You can see the full competition schedule online.
Even if you are not attending the London 2012 Olympic Games your travel in London is going to be affected as visitor numbers will increase dramatically and certain sections of the transport network will be under more stress than normal.
There is no spectator parking at any of the venues so you are advised to use public transport. All tickets for events in London include a one day London Transport Games Travelcard so your travel across London will be covered for the day.

Be aware, that the Olympic Park is huge (500 acres) so walking time between the venues will likely be longer than you expect.
As well as sporting events, don't forget we have the London 2012 Festival as part of the Cultural Olympiad and the Olympic Torch Relay from 19 May to 27 July and Paralympic Torch Relay is from 2 to 29 August.
