Boris Johnson will set out the route out of lockdown on February 22 after No10 sparked fears the timetable was slipping.
Home Office Minister Victoria Atkins said the much-anticipated roadmap for easing restrictions would be made in 10 days time.
Downing Street triggered confusion over the timetable on Thursday, when the Prime Minister's official spokesman would only say the plan would be shared "in the week of February 22."
The date is important as it is two weeks before March 8, when Mr Johnson hopes to begin reopening schools.

The news sparked concern that the timeline for the return to the classroom could be pushed back.
But Ms Atkins told Sky News: "On the February 22, the Prime Minister will make a statement to the House of Commons where he will set out our roadmap to ease lockdown."
Pushed her for clarity, she said: "We are expecting that announcement on 22 February."
She said next week would be "a critical week" for shaping the route out of lockdown, as the Government gathers data at home and abroad.
Schools are expected to be the first thing to reopen when restrictions begin to ease.
Robert Halfon, the Tory chairman of the education select committee, warned ministers that there could be no delay to getting children back in the classroom.
He told The Daily Telegraph: "We just need to make sure March 8 is signed in blood, not just a line in the sand."
Mr Johnson is also under pressure from lockdown-sceptic Tories to rip up all restrictions once the most vulnerable have been vaccinated.
Mark Harper, chairman of the Covid Recovery Group of Tory backbenchers, said keeping legal restrictions after all the over-50s and anyone over 16 with a health condition have been vaccinated would not be justifiable.
He told the BBC's Newscast podcast: "I think at that point, I don't think you can justify legal restrictions at all.
"We might still have advice and things, but actually legal restrictions on being able to meet the family and go out and things like that, I just don't think those are justifiable when you've protected the most vulnerable groups in society."
Reports emerged that ministers are considering keeping social distancing measures until at least the autumn, with people wearing face coverings and keeping a metre apart for months.
