¿Te queda bien el lunes?

In this sentence, quedar bien means something like to suit someone’s schedule, to be convenient, or to work well.

So ¿Te queda bien el lunes? is asking whether Monday is good for you.

This is a very common use of quedar in everyday Spanish. It does not mean physical location here, and it does not mean clothing fit here either.

A few useful meanings of quedar bien:

• Esta camisa te queda bien. → This shirt looks good on you / fits you well.
• El lunes me queda bien. → Monday works well for me.

So the exact meaning depends on context.

Because el lunes is the grammatical subject of the verb.

In ¿Te queda bien el lunes?, the structure is basically:

• el lunes = the thing being talked about
• te = to you
• queda bien = suits / works well

So literally, it is closer to:

Does Monday suit you well?

Since el lunes is singular, the verb is also singular:

• el lunes te queda bien
• not el lunes te quedas bien

Quedas would be the tú form, but here tú is not the subject. The subject is el lunes.

Te means to you.

It is an indirect object pronoun. In this sentence, Spanish uses a structure that is a bit different from English:

• ¿Te queda bien el lunes?
• literally: Does Monday suit you well?

So:

• me = to me
• te = to you
• le = to him/her/you formal
• nos = to us
• os = to you all
• les = to them/you all formal

Examples:

• Me queda bien el martes. → Tuesday works for me.
• Nos queda bien a las seis. → Six o’clock works for us.
• ¿Le queda bien mañana? → Does tomorrow suit you? / Would tomorrow be good for you?

In Spanish, days of the week often take the definite article el when talking about on Monday, on Tuesday, etc.

So:

• el lunes = on Monday / Monday
• el martes = on Tuesday / Tuesday

This is very normal Spanish.

Examples:

• Nos vemos el lunes. → See you on Monday.
• Trabajo el viernes. → I work on Friday.

If you make it plural, it usually means a repeated action:

• Trabajo los lunes. → I work on Mondays.

So in your sentence, el lunes refers to a specific Monday, usually one already understood from context.

Yes. That is completely natural.

Both are correct:

• ¿Te queda bien el lunes?
• ¿El lunes te queda bien?

The difference is mainly one of emphasis or focus.

• ¿Te queda bien el lunes? puts early attention on you
• ¿El lunes te queda bien? puts early attention on Monday

In conversation, word order in Spanish is often flexible, especially in questions.

Yes, very common.

In Spain, ¿Te queda bien...? is a natural and everyday way to ask whether a day or time is convenient.

Other common alternatives are:

• ¿Te va bien el lunes? → Does Monday work for you?
• ¿Te viene bien el lunes? → Would Monday be good for you?
• ¿Puedes el lunes? → Can you do Monday?

They are all useful, but ¿Te queda bien...? sounds very natural and idiomatic.

No. That is one of several meanings.

Quedar bien is very flexible. Common meanings include:

1. To suit someone / be convenient

   • El lunes me queda bien.
   • Monday works for me.

2. To look good on someone

   • Ese vestido te queda muy bien.
   • That dress looks very good on you.

3. To make a good impression / look good socially

   • Quedaste muy bien con tus suegros.
   • You made a very good impression on your in-laws.

So learners often need to rely on context.

Some common answers are:

• Sí, me queda bien. → Yes, that works for me.
• Sí, perfecto. → Yes, perfect.
• Sí, el lunes me va bien. → Yes, Monday works for me.
• No, no me queda bien. → No, that doesn’t work for me.
• Mejor el martes. → Tuesday would be better.
• El lunes no puedo. → I can’t on Monday.

A very natural mini-dialogue:

• ¿Te queda bien el lunes?
• Sí, me queda bien.

or

• ¿Te queda bien el lunes?
• No, mejor el martes.

Yes. Very often.

You can use this same pattern with days, times, and other arrangements:

• ¿Te quedan bien las cinco? → Does five o’clock work for you?
• ¿Te queda bien mañana? → Does tomorrow work for you?
• ¿Te queda bien ese horario? → Does that schedule suit you?

Notice something important:

• el lunes is singular, so queda
• las cinco is plural, so quedan

Compare:

• Te queda bien el lunes
• Te quedan bien las cinco

You will often hear bien with this expression, because it helps mean well / conveniently / fine.

• ¿Te queda bien el lunes? sounds complete and very natural.

You may also hear related expressions without bien, but they can sound slightly different depending on context:

• ¿Te queda el lunes? is less standard for this meaning and may sound incomplete to many speakers.
• ¿Te viene bien el lunes?
• ¿Te va bien el lunes?

So for learners, ¿Te queda bien el lunes? is the safest pattern to remember.

For formal you, change te to le:

• ¿Le queda bien el lunes?

That would be appropriate with someone you address as usted.

For plural you in Spain:

• ¿Os queda bien el lunes? → Does Monday work for you all?

For plural you in Latin American Spanish, or formal plural:

• ¿Les queda bien el lunes?

So the pattern changes mainly through the pronoun:

• me queda bien
• te queda bien
• le queda bien
• nos queda bien
• os queda bien
• les queda bien

Because standard Spanish uses both an opening and a closing question mark:

• ¿ ... ?

So:

• ¿Te queda bien el lunes?

The opening mark tells you from the start that the sentence is a question. This is normal punctuation in Spanish and should be used in writing.

The same happens with exclamations:

• ¡Qué bien!

So for learners, it is worth getting used to writing both marks, not just the final one.
