It means operating hours or hours of operation.

• 운영 = operation, running, management
• 시간 = time

So together, 운영 시간 refers to the hours during which something is operating. In store contexts, 영업시간 is also very common.

은 is the topic particle.

It marks 운영 시간 as the topic of the sentence, like:

As for the operating hours, they are the same on Friday too.

It is not exactly the same as an English subject marker. It tells the listener what the sentence is about, and sometimes it can also add a slight contrast depending on context.

It breaks down like this:

• 금요일 = Friday
• 에 = at/on
• 도 = also, too, even

So 금요일에도 means on Friday too or also on Friday.

Depending on the context, 도 can sometimes feel like even on Friday.

That is true. With days of the week, 에 is often optional.

So both of these can work:

• 금요일에도 같습니다
• 금요일도 같습니다

Using 에 makes the time relationship a little more explicit: on Friday too. In formal notices or written Korean, 금요일에도 sounds very natural.

Here, 같습니다 means is the same or are the same.

It is the formal polite form of 같다.

So the sentence means that the operating hours are the same on Friday as well.

Yes, 같다 can have more than one use.

Here it means to be the same / similar, not to seem.

That is because it is directly describing 운영 시간.

Compare:

• 운영 시간은 금요일에도 같습니다. = The operating hours are the same on Friday too.
• 비가 올 것 같습니다. = It seems it will rain.

The seems meaning usually appears in patterns like -것 같습니다.

Korean often leaves things unstated if the context already makes them clear.

So 같습니다 here means something like:

• the same as the other days
• the same as the usual hours
• the same as what was mentioned before

English often spells this out more, but Korean often relies on context.

Because Korean does not always need a separate verb like English is/are in the same way.

같습니다 already includes the idea of:

• being
• sameness
• politeness

So the sentence is complete without an extra word for are.

It uses the formal polite style, the -습니다 style.

This style is common in:

• signs
• announcements
• customer service language
• official notices

So it fits very well for something like posted operating hours.

Yes, it is natural and understandable, especially in a formal context.

Some common variations are:

• 운영 시간은 금요일도 같습니다.
  Same meaning, but without 에

• 영업시간은 금요일에도 같습니다.
  Often more natural for a store's business hours

• 운영 시간은 금요일에도 동일합니다.
  More formal; 동일합니다 means is identical / is the same

The best version depends on the situation.

A natural pronunciation is close to:

운영 시간은 금요일에도 같습니다
un-yeong si-gan-eun geum-yo-il-e-do gat-seum-ni-da

A few helpful pronunciation notes:

• 운영 sounds close to 우녕
• 금요일 sounds close to 그묘일
• 같습니다 sounds close to 갇씀니다

In natural speech, it flows together rather than being pronounced syllable by syllable in a stiff way.
