Please refer to 'Planned Duration' section of create project documentation for the same.
Below is the excerpt from documentation:
The expected duration of this project. After you add tasks, this field is calculated from the duration of the tasks. The duration also considers the project schedule, accounting for any non-work time in the schedule.
Note: For example, if the default schedule is used, with a standard 8-hour work day, a project that starts at 8 A.M. on July 1 and ends at noon on July 2 is calculated as 1 day and 4 hours, not 28 hours.
Any project or project task with no children is restricted to a maximum duration of 1500 days.
