Cards and tributes have been left in the High Street doorway where the much-loved busker performed with his trademark battered guitar.
Jim, whose real name was Anthony Bowen, died on Monday after suffering cardiac arrest.
Today funeral director John Coggles said his service will take place at Kings Lynn Minster on Wednesday, February 15 (12.30pm).
'Everyone who wishes to pay their last respects is welcome to attend,' he said. 'The service will be followed by a private burial, within his dad's grave at Gayton churchyard.'
Earlier West Norfolk council said it would consider putting up a plaque to remember him, as it asked people to refrain from leaving any more tributes.
Council leader Brian Long said: 'We were all very sad to hear that Mr Bowen had died – there can't be many people who regularly come to King's Lynn who don't know Juggling Jim. He was one of our town's best-known characters and he will be missed by many.
'We have been contacted by a few people who've expressed a wish that some kind of memorial, possibly a plaque, to Jim be put up where he often performed his act. If this is something there is a lot of local support for, we'd like to try and make it happen. We'd be happy to contact the owners of the building, to see what could be possible.
'We would ask that no more flowers or mementoes be left at the spot where Juggling Jim performed. We have to make the difficult decision of when to clear these away, and while we completely understand the depth of feeling that has prompted people to leave them, the doorway is a fire exit for nearby businesses, and we can't allow their safety to be put at risk.
'We're aware that a crowdfunding page has been raising money to go towards Mr Bowen's funeral costs, or a memorial, and I'd like to invite the organiser to get in touch. Donations have also been made in cash, and if I can help to get these two funds together so they can do the most good, I'd like to do that'.
The doorway at 84 High Street where he performed already has a plaque on one side remembering the 18th Century composer Charles Burney and his daughter Fanny, who was a novelist.
A few hundred yards away, a plaque on the side of the Duke's Head Hotel remembers Britain's first prime minister Sir Robert Walpole (1676 - 1745) who celebrated his election victories in its bar.
