For a masters program? Very early for September 2024 because the schools typically start looking at candidates mid-winter semester for September admission unless you are an exceptional student and they want to ensure they lock you in as a student. Most programs send out some conditional offers before grades are available in May and the rest after May grades are available. Although you are applying and have finished school many applicants are still in school applying for masters degree next year. Depending on the program and how big it is and how competitive it is I would expect first round offers to go out in March/April.
