저는 is the polite way to say I, and -는 marks the topic.

• 저 = polite I
• 는 = topic marker, like as for me

So 저는 gives the feeling of as for me, ...

Why not the others?

• 나는: same structure, but 나 is casual, so it would be less polite.
• 제가: uses the subject marker -가, which often emphasizes I as the subject. That can sound more like I am the one who...

In this sentence, 저는 is natural because the speaker is simply talking about their routine.

아침마다 means every morning.

The key part is -마다, which means every or each when attached to a noun.

Examples:

• 아침마다 = every morning
• 주말마다 = every weekend
• 해마다 = every year

So 아침마다 expresses a repeated habit.

Yes, but only slightly.

Both can mean every morning.

• 아침마다 focuses on each morning
• 매일 아침 literally means every day, in the morning

In many everyday situations, they are interchangeable.
Here, 아침마다 sounds very natural for a repeated routine.

Because 달력 is the direct object of 보다 in 보면서.

• 달력 = calendar
• 보다 = to look at / to see
• 달력을 보다 = to look at the calendar

So -을/를 marks what is being looked at.

In casual speech, Koreans sometimes drop object particles, so you may also hear 달력 보면서, but 달력을 보면서 is grammatically complete and very natural.

보면서 comes from 보다 + -면서.

• 보다 = to look at
• -면서 = while doing, as one does

So 보면서 means while looking at.

In this sentence:

• 달력을 보면서 = while looking at the calendar

It shows that the speaker checks the day’s plan at the same time as looking at the calendar.

-면서 connects two actions done by the same subject at the same time.

Here, the same person is doing both actions:

1. looking at the calendar
2. checking the day’s plan

So the structure is:

• 달력을 보면서
• 하루 계획을 확인해요

This means something like:

• I check my daily plan while looking at the calendar.

A useful point: -면서 usually implies the subject of both actions is the same.

Because there are two different verbs, and each one has its own object.

1. 달력을 보면서
   • 달력 is the object of 보다
2. 하루 계획을 확인해요
   • 하루 계획 is the object of 확인하다

So even though the sentence is one whole sentence, it contains two verb phrases:

• calendar + look at
• day plan + check

That is why two object markers are completely normal here.

In this sentence, 하루 계획 means the plan for the day or daily plan.

• 하루 = one day / a day
• 계획 = plan

When Korean puts nouns together like this, the relationship is often understood from context. Here, it does not mean a special one-day plan in a technical sense. It simply means the plans or schedule for that day.

A natural English translation would be:

• my plan for the day
• my daily schedule
• the day’s plan

Because Korean often leaves out possession when it is obvious from context.

In English, we often need my:

• I check my daily plan

In Korean, if the speaker is clearly talking about their own routine, 하루 계획 is enough.

You could say 제 하루 계획을 확인해요, but it may sound a little more explicit than necessary. The original sentence sounds natural and smooth.

확인해요 means check, confirm, or verify.

• 보다 / 봐요 = to look at, to see
• 확인하다 / 확인해요 = to check carefully, confirm, make sure

So:

• 달력을 봐요 = I look at the calendar
• 계획을 확인해요 = I check/confirm the plan

Using 확인해요 shows that the speaker is not just glancing at the plan, but reviewing it to make sure what they need to do.

확인해요 is in the 해요-style, which is polite and very common in everyday conversation.

The verb is:

• dictionary form: 확인하다
• polite everyday form: 확인해요
• formal style: 확인합니다

So this sentence is polite but not stiff. It sounds like normal spoken Korean.

Yes. Korean often omits the subject or topic when it is clear from context.

So you could simply say:

• 아침마다 달력을 보면서 하루 계획을 확인해요.

That would still sound natural, especially if it is already obvious who is speaking.

Korean frequently leaves out words like I, you, my, and the when the meaning is understood.

A helpful way to read it is in chunks:

• 저는 = as for me
• 아침마다 = every morning
• 달력을 보면서 = while looking at the calendar
• 하루 계획을 = the plan for the day
• 확인해요 = check

So the structure is:

As for me / every morning / while looking at the calendar / the day’s plan / I check.

Korean word order is often different from English, but if you read it in chunks like this, it becomes much easier to follow.
