It will be hosted by Buckinghamshire County, Aylesbury Vale District and Aylesbury Town councils.
Bishop of Buckingham the Rt Rev Alan Wilson will give an address at the service which will be led by the Rev Doug Zimmerman, Rector of Aylesbury.
The service, which starts at 4.30pm, and has seating for 500, will be open to residents.
Buckinghamshire's Lord Lieutenant, Sir Henry Aubrey-Fletcher, said that Buckingham Palace were not encouraging 'Jubilee style' celebrations for this occasion, and it will be a normal working day for the Queen.

HM the Queen will mark the day she becomes Britain’s longest reigning monarch by opening the UK's biggest new domestic railway line for more than a century.
