Mace was due to finish the new ground by last September but it will now be ready by the first week of April.
Spurs first opponents will depend on the progress of Brighton in the FA Cup.
If Brighton win their FA Cup quarter-final match on Sunday 17th March Spurs play Crystal Palace on Wednesday 3rd April.
If Brighton lose their FA Cup quarter-final match Spurs will play them on 6th/7th April (subject to Champions League scheduling).
The club has also confirmed two Test Event matches at the new stadium to achieve a formal safety certificate.
The two matches will feature the club’s Academy side and a Legends team on March 24 and 30.
Chairman, Daniel Levy, told the club’s website: “We are delighted that we shall be able to welcome our supporters to the stadium and our players of the past and the future to take to the pitch on what will be momentous occasions for our Club.
“Please do come and see your new stadium and share these moments.
“Thank you all once again. Your support has been much appreciated during a challenging but exciting time.”
