Following discussions in Brussels on Thursday, the offices of Brexit Secretary David Davis and the European Commission's chief negotiator Michel Barnier released a joint statement to confirm the date.
His comments are likely to be seen as a further indication he is pressing for the Government to take a "softer" line on Brexit than the immigration-driven approach previously set out by Theresa May.
"We should be protecting jobs, protecting economic growth and protecting prosperity", Hammond said as he arrived for a meeting of European Union finance ministers in Luxembourg. She also said: "I am equally clear that no deal for Britain is better than a bad deal for Britain".
"As we enter negotiations next week we will do so in a spirit of honest cooperation taking a pragmatic approach to trying to find a solution that works both for the United Kingdom and for the European Union 27", he said.
The new United Kingdom government is yet to take a final shape despite announcement of new Cabinet members as a final deal with the Northern Irish Democratic Unionist Party (DUP) gets worked out.
DUP leader Arlene Foster insisted that any deal with the Conservatives would not undermine the province's peace accords.
The EU wants to secure the rights of more than three million Europeans living in Britain - and over one million Britons living on the continent.
Monday's negotiations are to open at 11:00am in Brussels (0900 GMT) with 90 minutes of talks between Barnier and Davis, followed by a working lunch between the pair and a press conference.
Among topics that need to be agreed upon is the status of United Kingdom citizens living and working in the EU, as well as that of European nationals doing the same in Britain.

Thomas' unprecedented round was all the more remarkable for the fact it featured two bogeys, at the fourth and 10th. He then backed it up with a second-round 64 and holds the tour scoring records for 36, 54 and 72 holes.
The Liberal Democrats, the fourth-biggest group in the British parliament, urged May to form a cross-party committee to negotiate Brexit.
The prospect of Brexit has sent a wave of concern through Britain's business sector.
"All the options are balanced and come with obligations", an European Union official working on Brexit said, noting that May had seemed to be looking for a sweeping free trade deal like that agreed past year with Canada but that some of those calling for "soft" Brexit cited arrangements such as those with Norway and Turkey.
A spokeswoman for the Brexit department said: "We have said consistently that resolving the status of European Union citizens living in the United Kingdom and UK nationals living in other member states is our first priority for negotiations".
"Depending on a hard or soft Brexit, that number might be slightly less than that, so it's going to be updated all the time", its United Kingdom chief executive Ian Stuart told BBC television.
Hammond, who has long-warned that a "hard Brexit" will affect the City, does have a point.
German Finance Minister Wolfgang Schaeuble said in a Bloomberg Television interview this week that as soon as "the principles" of Brexit are agreed, talks can move on in parallel to "the details of the regulation, and what will be the further relations between the United Kingdom, after Brexit, and the single market and the European Union, and so on".
"And actually, getting over the fence, there might be some fresh grass out there".
