予定だScheduled plan
予定だ presents an action or event as a plan or schedule that has already been arranged. It works for personal plans as well as timetables and organizational plans.
Personal plans
Use the dictionary form for an action that is planned, and the plain negative form when the plan is not to do something.
A plan, not just a wish
予定だ suggests that the plan has some concrete shape: a date has been chosen, arrangements have been made, or the action has been placed on a schedule. The plan can still change; the form does not promise that it will definitely happen.
Organizational schedules
The person making the plan does not have to be the main point. Announcements and schedules often focus on the planned event itself.

Plan, intention, or established arrangement?
Choose 予定だ when the schedule or concrete plan matters. Choose つもりだ when personal resolve is central, and ようと思っている when describing an intention someone continues to hold or consider. ことになっている instead emphasizes that an arrangement or rule has already been established, often by circumstances or an organization.
