Have or is having?

I came across this sentence:"My band has two shows this weekend" from a book.
I was wondered if using the sentence below is correct and have the meaning similarly as the above sentence
" My band is having two shows this weekend"
I thought that "this weekend" means a plan in the future so we should use the present continuous tense. Why did they use the present Simple tense?
Thanks in advance.

I thought that "this weekend" means a plan in the future so we should use the present continuous tense.

No, it's quite acceptble to use the present tense when something is obviously in the future.
We have multiple existing discussions on the use of the present to express the future.
See, for example: present simple expressing future

Then is the sentence below correct?

" My band is having two shows this weekend"

Yes. That’s perfectly fine and natural.

" My band is having two shows this weekend"

It's grammatically correct, but much less idiomatic than the present simple. If you're talking about engagements in your schedule, "have" seems far more natural.
