The organisation said in a statement: "Mr Sinner will serve his period of ineligibility from 9 February 2025 to 11.59pm on 4 May 2025.".
Tennis world number one Jannik Sinner has been banned for three months over doping.
It means Sinner will be eligible to return to competitive tennis before the French Open which starts in late May.
The Italian player tested positive for a banned substance last year.
He has now accepted the ban and settled his case with the World Anti-Doping Agency (WADA).
