Her Majesty The Queen is celebrating 70 years of service, making her the longest-reigning monarch in United Kingdom history.

Buckingham Palace says the United Kingdom will be celebrating a four-day bank holiday in honour of Queen Elizabeth II's 70 years on the throne. February 6 marks the Platinum Jubilee.

Concerts, a pudding contest, and parades are part of the expected fanfare, but so is a special church service.

On Friday, June 3, a Service of Thanksgiving will be held at St Paul’s Cathedral. The release says the service is in thanksgiving for The Queen's reign. No other details are being shared yet, but this is the only official Platinum Jubilee event scheduled for the entire day.

The Queen celebrated her Diamond Jubilee with a Service of Thanksgiving in 2012.

The Queen has a strong Christian faith, often sharing the gospel and her personal love of God.

During this year's Christmas message, The Queen said "it is this simplicity of the Christmas story that makes it so universally appealing: simple happenings that formed the starting point of the life of Jesus, a man whose teachings have been handed down from generation to generation, and have been the bedrock of my faith”.

Most U.K residents will have Thursday, June 2 to Sunday, June 5 off.

"The bank holiday will provide an opportunity for communities and people throughout the United Kingdom to come together to celebrate the historic milestone," a media release from Buckingham Palace says.

Part of the proposed summer festivities includes "The Big Lunch" inviting people to host events, a parade for the Queen's June 11 official birthday, and a pageant.
