에 marks the location where something exists. In this sentence, 안내문에 means on the notice / in the announcement / on the sign.

So the structure is basically:

• 안내문에 = on the notice
• 오늘 일정표가 = today’s schedule
• 있어요 = exists / is there

Korean uses 에 with 있다 to show where something is located.

Here, 가 is the subject marker, and it is commonly used with 있어요 when introducing or pointing out that something exists.

So 오늘 일정표가 있어요 is like saying:

• There is today’s schedule
• Today’s schedule is there

If you used 는, it would sound more like you are setting today’s schedule up as the topic for contrast or further explanation. For example, 오늘 일정표는 안내문에 있어요 would mean something like As for today’s schedule, it’s on the notice.

In this sentence, 가 is the most natural choice.

Both 오늘 일정표 and 오늘의 일정표 can work.

• 오늘 일정표 = today schedule
• 오늘의 일정표 = today’s schedule

In Korean, 의 is often omitted in everyday speech and writing when the meaning is already clear. So 오늘 일정표 sounds natural and concise.

You may still see 오늘의 일정표 in more formal writing, titles, or signs.

있어요 is the polite present form of 있다, which can mean to exist, to be, or to have, depending on context.

In this sentence, it means there is / is located.

So 안내문에 오늘 일정표가 있어요 literally has the sense of:

On the notice, today’s schedule exists.

Natural English turns that into something like:

Today’s schedule is on the notice.

Korean often puts the location first, then the thing that exists, and finally the verb.

So this sentence is structured like:

• 안내문에 = on the notice
• 오늘 일정표가 = today’s schedule
• 있어요 = exists / is there

Literal order: On the notice, today’s schedule exists.

English usually prefers: Today’s schedule is on the notice.

So the Korean word order is normal even though it sounds unusual when translated word-for-word.

Use 에 with 있다 because 에 marks the place where something exists.

• 에 = at/in/on a place, especially with existence or destination
• 에서 = at/in a place where an action happens

Since 있어요 is not an action like study, eat, or work, 에 is correct.

For example:

• 교실에 학생이 있어요. = There is a student in the classroom.
• 교실에서 공부해요. = I study in the classroom.

It can correspond to in, on, or sometimes at depending on natural English phrasing.

Korean 에 is broader than any one English preposition. With something like 안내문 (notice, announcement, posted information), English often says on:

• on the notice
• on the announcement
• on the posted information

So even though Korean just uses 에, the best English choice is often on here.

안내문 usually means a notice, announcement, information notice, or posted guide text.

It is made from:

• 안내 = guidance / information
• 문 = writing / text / document

So 안내문 is some written information given to people, such as a posted notice at school, an office, an event, or a public place.

일정표 means a schedule or timetable.

It is made from:

• 일정 = schedule, itinerary, plan
• 표 = chart, table, list

So 오늘 일정표 means today’s schedule or today’s timetable.

Depending on context, it could refer to a class schedule, event schedule, travel schedule, or daily plan.

It is polite informal style because it ends in -어요.

• 있어요 = polite everyday speech
• 있습니다 = more formal
• 있어 = casual/intimate

So this sentence is appropriate in normal conversation or polite everyday communication.

Examples:

• 안내문에 오늘 일정표가 있어요. = polite, natural
• 안내문에 오늘 일정표가 있습니다. = more formal
• 안내문에 오늘 일정표가 있어. = casual

Yes, that is a possible way to understand it in English.

Korean 있다 can sometimes feel like there is and sometimes like has, depending on context. So this sentence could be interpreted as:

• There is today’s schedule on the notice.
• The notice has today’s schedule on it.
• Today’s schedule is on the notice.

The last version is usually the most natural English translation, but the others help show how the Korean structure works.

Yes. Adding 는 after 에 gives 에는, which adds topical or contrastive nuance.

• 안내문에 오늘 일정표가 있어요. = neutral statement
• 안내문에는 오늘 일정표가 있어요. = As for/on the notice, today’s schedule is there

Using 에는 can suggest contrast, such as implying that the schedule is on the notice, maybe not somewhere else. Without context, the original 안내문에 is simpler and more neutral.
