I have an existing project file (.mpp file). I realized that duration of all tasks is one day longer comparing to my estimation. For example, a task with duration 2 days starting at 3.6.2019 is scheduled to finish at 5.6.2019. After checking resource usage I realized that Project schedules only 7 hours for the first day of the task (3.6.2019). For the second day (4.6.2019) Project schedules 8 hours and the remaining one hour schedules for the third day (5.6.2019). This applies for all tasks within the project - work for the starting day of the task is always scheduled for 7 hours only. All tasks use fixed duration type, and all are automatically scheduled. Standard calendar with 8 working hours per day is used. What is the reason that Project schedules only 7 hours for first day of every task?
Update: I see that Project schedules the first day from 9:00 to 17:00, but all other days schedules from 8:00 to 17:00. Default start time of project calendar is set to 9:00 and default end time of project calendar is set to 18:00.
