Prime Minister Boris Johnson has encouraged members of the public to clap for Captain Sir Tom Moore at 18:00 GMT on Wednesday.
The 100-year-old, who raised almost £33m for NHS charities by walking laps of his garden, died with coronavirus in Bedford Hospital on Tuesday.
Mr Johnson said the clap would also be for "all those health workers for whom he raised money".
Capt Sir Tom's family said they were "incredibly touched".
In a statement on Twitter, they said they would be "taking part with huge love in their hearts for their father, grandfather and father-in-law".
Dozens of tributes have been left outside his home in Marston Moretaine, Bedfordshire.
Meanwhile at least 10 petitions calling for a state funeral for the late Army veteran, have been started on the website Change.org.
The only non-Royal to be paid such an accolade in recent times was former Prime Minister Sir Winston Churchill in 1965, though ceremonial funerals, which observe many of the same traditions were held for Diana, Princess of Wales and Margaret Thatcher.
Other petitions have called for a statue, a minute's silence, a burial in Westminster Abbey and a 21 gun salute or flypast.
The Army veteran won the nation's hearts by walking 100 laps of his garden last spring during the first coronavirus lockdown, raising money for NHS Charities Together.
Capt Sir Tom tested positive for Covid-19 last week. His family said due to other medication he was receiving for pneumonia, he was unable to be vaccinated.
The charity said the total would rise to £39m when Gift Aid was taken into account.
A weekly applause for front-line NHS staff and other key workers ran for 10 weeks during the UK's first lockdown.
Before Prime Minister's Questions earlier, the House of Commons held a one-minute silence in memory of Capt Sir Tom and those who have lost their lives as a result of the pandemic.
In the government's afternoon press conference, Mr Johnson said: "Tonight let's clap together for Captain Tom at 18:00 and let's clap for the spirit of optimism that he stood for.
"But let's also clap for all those he campaigned for - our brilliant NHS staff and care workers - and let's do everything we can to carry on supporting them. "Because if we stay at home, protect our NHS and save lives then, in the words of Captain Tom, tomorrow will be a good day."
Labour leader Sir Keir Starmer added Capt Sir Tom "embodied the spirit of Britain" and welcomed the announcement.
A silence was also held in the House of Lords. Leading the tribute, the Lord Speaker Lord Fowler said: "His quiet resolve and selfless spirit of public service will never be forgotten.
"As we pause to remember him and his enduring legacy, we also remember all those who have died since the start of the pandemic."
The family of Capt Sir Tom, originally from Keighley in West Yorkshire, said the last year of his life was "nothing short of remarkable".
They added that he had "experienced things he'd only ever dreamed of".
A BBC News special, Captain Tom: We Salute You, presented by Michael Ball, is being broadcast on Wednesday at 19:30 GMT on BBC One and will be available on the BBC iPlayer.
