Questions & Answers about sono ibento ha raisyuu no kinyou ni kaisaiyotei da ga, nittei ha henkou ni naru kamo sirenai.

Why does the sentence use は twice (in そのイベントは … and 日程は …)?

• The first は sets the overall topic: “As for that event…”
• The second は is contrastive: “As for the schedule (at least), it might change.”
• Using 日程は draws attention to the schedule as the specific thing that may change, contrasting it with the earlier statement.
• You could also say 日程が変更になるかもしれない, which is more neutral/new-information; 日程は feels like “speaking of the schedule in particular…”

What’s the difference between 来週の金曜 and 来週の金曜日?

• 金曜日 (きんようび) is the full form; 金曜 (きんよう) is a common written/spoken abbreviation.
• Both are natural. 金曜 is terse and common in schedules, headlines, and casual contexts; 金曜日 sounds a bit fuller/neutral.
• Other natural variants: 来週金曜, 来週の金曜日. All mean the same thing here.

Why is に used after 金曜? Can I omit it?

• に marks a specific point in time: 金曜に = “on Friday.”
• With specific dates/days, に is often used but can be omitted in speech without changing meaning much: 来週の金曜(に)開催予定.
• Don’t use に with relative-time words like 今日/明日/来週 alone (you say 明日行く, not ×明日に行く), but with exact times/days に is standard and safe.

What exactly does 開催予定 mean?

• 開催 (かいさい) = “holding/hosting (an event)” (a noun/nominal).
• 予定 (よてい) = “plan/schedule.”
• The compound 開催予定 means “scheduled to be held.” So 開催予定だ = “It is scheduled to be held.”

Is 開催する予定だ okay here?

• If the topic is the event itself (イベント), saying イベントは開催する予定だ is awkward because it makes the event the doer of “hold.”
• Better options when the event is the topic:
  • イベントは開催される予定だ (passive: “will be held”)
  • イベントは開催予定だ (compound noun: natural and concise)
• Use [Agent] はイベントを開催する予定だ when the subject is the organizer.

What’s the role and tone of だが compared to けど/だけど/しかし/でも?

• だが = “but” in a somewhat formal/written or stiff tone.
• けど/だけど = conversational, very common in speech.
• しかし = formal/logical connector, often sentence-initial.
• でも = “but/however,” usually starts a new sentence.
• The sentence could be made more conversational as: …開催予定だけど、日程は…

Why use 日程 instead of 予定, 日付, or スケジュール?

• 日程 (にってい) = the timetable/itinerary/date arrangement (what happens on which day). Very natural for events.
• 予定 (よてい) = plan/arrangement broadly (not necessarily tied to a specific calendar date).
• 日付 (ひづけ) = the calendar date (e.g., 10/21); narrower than 日程.
• スケジュール = schedule (loanword), casual/neutral; fine, but 日程 is more standard/formal for event dates.

What does 変更になる mean, and how does it differ from 変更される and 変更する?

• 変更になる = “to become changed” (resulting state, no explicit agent; neutral/impersonal).
• 変更される = passive “to be changed” (also impersonal, slightly more formal/explicit).
• 変更する = active “to change” (someone/organization changes it): e.g., 主催者が日程を変更する.
• In announcements, 変更になる/される are preferred to avoid naming an agent.

Why is に used after 変更 in 変更になる?

• It’s the pattern X に なる = “to become X” (resulting state).
• Here, 変更 is the resulting state the schedule will become: (日程が) 変更に なる.

Could I say 日程が instead of 日程は?

• Yes: 日程が変更になるかもしれない is fine and neutral (introducing new info).
• 日程は is contrastive/topical: it implies “at least regarding the schedule” or contrasts it with the previous clause. Both are correct; pick based on nuance.

How strong is かもしれない? Are there polite or casual variants?

• かもしれない = “might/may” (uncertain possibility; often felt as a lower-to-middling probability).
• Casual: かも (e.g., 変わるかも).
• Polite: かもしれません.
• かもです is generally not standard. かもしれないです is common in speech but some teachers prefer かもしれません in polite contexts.

How does かもしれない attach to different word types?

• It follows the plain/dictionary form:
  • Verb: 行くかもしれない, 変わるかもしれない
  • い-adj: 高いかもしれない
  • Noun/な-adj: drop だ before it: 学生かもしれない, 静かかもしれない
• With casual かも, you can say 学生かも, 静かかも, 行くかも.

Why is it だ and not です? How would a polite version look?

• だ is plain style. For polite/formal, use です/ます forms:
  • そのイベントは来週の金曜日に開催予定ですが、日程は変更になるかもしれません。
  • Or: …開催される予定ですが… for the passive version.

Are the spaces between Japanese words normal?

• No. Standard Japanese writing does not insert spaces between words.
• They were added here for learner readability. A normal version: そのイベントは来週の金曜に開催予定だが、日程は変更になるかもしれない。

Can I move the time phrase to another position?

• Yes. Natural options include:
  • 来週の金曜に、そのイベントは開催予定だが…
  • そのイベントは、来週の金曜に開催予定だが…
• Time expressions are flexible in Japanese; place them early for clarity/emphasis.

Is だ required before が after a noun like 開催予定?

• Yes. With nouns/な-adjectives, you need だ before the conjunctive が: 開催予定だが.
• With けど/けれど(も), だ is often dropped in casual speech: 開催予定だけど (both 静かだけど/静かだけど are heard).

How do you read the key kanji, and is writing かもしれない with kanji okay?

• Readings: 来週 (らいしゅう), 金曜 (きんよう), 開催 (かいさい), 予定 (よてい), 日程 (にってい), 変更 (へんこう).
• かもしれない is usually written in kana. かも知れない exists but is less common in modern writing.

Could I use 可能性がある or 恐れがある instead of かもしれない?

• Yes, both are more formal:
  • 日程が変更になる可能性がある = “there is a possibility…”
  • 日程が変更になる恐れがある = “there is a risk/danger…” (stronger/negative flavor)
• かもしれない is neutral and broadly usable.

Can I just say 日程が変わるかもしれない instead of 変更になるかもしれない?

• Yes. 変わる is the everyday verb “to change” and sounds more conversational.
• 変更になる sounds a bit more formal/announcement-like. Both are natural.

Is となる an alternative to になる here?

• In formal notices you’ll often see 変更となる. It’s similar to 変更になる but feels more formal/official and slightly more impersonal:
  • 日程は変更となる場合がございます。
