Notes
Related patterns
Similar
Both report arrangements the speaker does not claim to have willed — 予定だ cites a calendar entry, ことになった cites a decision handed down; only ことになる also carries the "it turned out that" reading.
Identical host (dictionary form＋だ) and identical gloss "plan to," but つもり asserts inner resolve while 予定 cites a schedule — inanimate subjects take 予定 only (電車は五時に出る予定だ／×つもりだ).
Lookalikes
Both ride dictionary form＋[noun]だ and translate "is supposed to" — 予定だ cites an external schedule anyone can check, はずだ the speaker's own inference; a broken 予定 was rescheduled, a broken はず was misjudged.
