kaigi ha kuzi ni owaru yotei desu

It is read:

かいぎ は くじ に おわる よてい です

Word by word:

• 会議 = かいぎ = meeting
• は = topic particle
• 九時 = くじ = nine o’clock
• に = time particle
• 終わる = おわる = to end
• 予定 = よてい = plan / schedule
• です = polite copula

Also, in normal Japanese writing, this would usually be written without spaces:

会議は九時に終わる予定です。

は marks 会議 as the topic of the sentence.

So the sentence is talking about the meeting, and then giving information about it:

• As for the meeting, it is scheduled to end at nine.

This does not always match English subject exactly. It is more like:

• Speaking of the meeting...

In many cases, English learners first think of は as is, but it is better to think of it as a topic marker.

に marks a specific point in time.

Here, 九時に means:

• at nine o’clock

Since 九時 is an exact clock time, に is natural and standard.

Examples:

• 七時に起きます = I wake up at 7.
• 三時に始まります = It starts at 3.

So in your sentence:

• 九時に終わる = end at 9:00

Because when a verb comes before a noun in Japanese, it normally uses the plain form, not the polite -ます form.

Here, 終わる directly modifies the noun 予定:

• 終わる予定 = a plan/schedule to end

This is the same grammar pattern as:

• 行く予定 = plan to go
• 帰る時間 = time to go home
• 食べる人 = person who eats

The polite part appears at the end of the sentence:

• 予定です

So:

• 終わる予定です = correct
• 終わります予定です = not correct

予定 means plan, schedule, or arrangement.

When used as:

• verb + 予定です

it means:

• is scheduled to...
• is жоспарred to...
• is expected to... in the sense of a schedule, not just a guess

So:

• 終わる予定です = is scheduled to end

This often sounds a bit more like an official or arranged plan than just a personal intention.

Grammatically, Japanese uses the non-past form here:

• 終わる
• です

But in meaning, the sentence usually refers to the future:

• The meeting is scheduled to end at 9.

Japanese often uses the non-past form for both:

• present
• future

So you understand the time from context.

Because 終わる is directly modifying 予定.

In Japanese, a verb can come before a noun and describe it. This is similar to a relative clause in English.

So:

• 終わる予定 literally = the plan that it will end
• natural English = scheduled to end

There is no の or other particle needed there.

This structure is very common:

• 行く予定 = plan to go
• 買う予定 = plan to buy
• 始まる時間 = time when it starts

This is a very common pattern in Japanese.

Inside the sentence, before a noun like 予定, the verb stays in plain form:

• 終わる予定

Then the whole sentence ends politely:

• 終わる予定です

So you can think of it like this:

• the inside grammar is plain
• the sentence ending controls the politeness level

This is why Japanese often mixes:

• plain form before nouns
• polite form at the end

The difference is mainly one of nuance.

会議は九時に終わります

• The meeting ends at 9.
• A straightforward statement.

会議は九時に終わる予定です

• The meeting is scheduled to end at 9.
• Emphasizes the plan or schedule.

So 予定です adds the idea that this is the intended or scheduled time, not necessarily a guaranteed fact.

For example, a meeting may be scheduled to end at 9, but in reality it might run late.

It implies a schedule or plan, so it is not a 100% guarantee.

It means something like:

• According to the schedule, the meeting should end at 9.

That sounds fairly solid, but it still leaves room for reality to be different.

So if the meeting goes long, the original sentence was not “wrong” — it was just describing the plan.

Both can be possible, but they give slightly different nuance.

会議は九時に終わる予定です

• As for the meeting, it is scheduled to end at 9.
• Good when the meeting is already the topic.

会議が九時に終わる予定です

• The meeting is the thing that is scheduled to end at 9.
• Can sound more like identifying the subject, depending on context.

For many learners, a simple way to think about it is:

• は = topic / “as for...”
• が = subject / identifying what does it

In this sentence, は is very natural because the speaker is talking about the meeting as the topic.

Yes, 九時 means nine o’clock, usually understood as a specific time point.

By itself, it does not tell you:

• AM or PM

That comes from context.

If you need to be explicit, you can say:

• 午前九時 = 9 AM
• 午後九時 = 9 PM

So:

• 会議は午後九時に終わる予定です = The meeting is scheduled to end at 9 PM.

Usually, つもりです is used more for a person’s own intention:

• 明日勉強するつもりです = I intend to study tomorrow.

予定です is used more for a plan, arrangement, or schedule:

• 会議は九時に終わる予定です = The meeting is scheduled to end at 9.

So for a meeting schedule, 予定です is the more natural choice.

If you used つもりです with 会議, it would sound odd in many contexts, because a meeting does not really “intend” to do something the way a person does.
