be going to vs present continous

rashinI'm cleaning the house on Friday. I'm going to clean house on Friday.

Both are fine. For most actions the two are equivalent in meaning.

I'm cleaning the house on Friday.
I'm going to be clean the house on Friday.

Because both sentences talk about the near future, I'd say they are the same. I've never understood this use of the present continuous though: It makes no sense to say that you're doing something in the future, unless you're looking into a crystal ball, predicting your future.

Hello dear teacher, Nice to see your reply again

How about this :

I'm going to have a baby in next two years. "have" in this sense is not used in continuous function.Am I right?
I can't say: I'm having a baby in next two years.

I'm graduating in next two years.

Thanks in advance

rashinI'm going to have a baby in next two years. "have" in this sense is not used in continuous function.Am I right?

That's right. The sentence states that you intend to have a baby in the future. This is how I would write the sentence.

rashinI can't say: I'm having a baby in next two years.
I'm graduating in next two years.

Thanks for swift reply .I have a question considering your sentences:

Aspara GusMany teachers here, I expect, would tell you that those sentences are OK, and so would many credible grammar sources. When I tell you that it's incorrect, I mean that I find it illogical and that I don't recommend it.

What's the usage of "would" here?

rashinWhat's the usage of "would" here?

It's used hypothetically. It means that if you consulted them or they replied to the topic, they would likely tell you the sentences are OK.

Thank you very much.

Aspara GusI've never understood this use of the present continuous though

All of the Engliish ways of expressing the future involve a present or past tense form:

Emma flies to India next Monday. Present Simple of FLY
Emma is flying to India next Monday. Present Progressive of FLY

Emma is going to fly to India next Monday.
