The organizers of the game confirmed that this would be the first time it will ring outside its regular hours since the funeral of King George VI in 1952.
It would be a live performance as the bells will need to be rung by hand, as Keeper of the Great Clock, Mike McCann stated.
This calls for celebration and innumerous tourists will line up in front of Big Ben on the day.
Big Ben clock is not the only one. Thousands of bells across Britain, from the Shetland Islands north of Scotland to the UK's church in Cornwall, will join in.
All permissions needed have been granted by the Parliament and Big Ben will chime 42 times between 8:12 (0712 GMT) and 8:15 a.m. on July 27.
The bells at the National Assembly for Wales, Stormont in Northern Ireland and the Scottish Parliament in Edinburgh will also ring at 8:12 a.m.
"We need to manually lift the brake that controls the weight that drives the mechanism that strikes Big Ben," McCann added.
"It is a sign of how special this summer is when one of the world's most famous bells will ring outside its regular schedule so it can be part of this London 2012 Festival commission to ring in the Olympic Games" said House of Commons Speaker, John Bercow told Reuters.
Experts feel that more than 10 million listeners will tune in when the three-minute chime will be broadcast to TV, radio and online.
Such is the hype for the occasion that thousands of participants have already signed up to join in, including the Royal Navy, the Mayor of London and the famous Whitechapel Bell Foundry in east London.
Musician Martin Creed will device the chiming sequence, entitled "All the Bells," as a part of a mega event.
