1. I don't have any special plans for this weekend.

2. I don't have any special plans during this weekend.
3. I don't have any special plans on this weekend.
4. I don't have any special pans this weekend.
===========================================
Which ones are correct? I think #3 is incorrect, for we should not put 'on' before 'this winter', 'this month', 'this weekend', etc. Am I right?

What about #1 and #2? Can we use both?

Is 'for this weekend' used as an adjective phrase or an adverb phrase in Sentence 1?

In #4, this weekend is an adverb phrase. What is the difference between #1 and #4?

Yes, #3 Is Incorrect. But what do you think is correct?
I think the rest are all correct.
1. I don't have any special plans for this weekend.
This one is commonly used, isn't it?
Is 'for this weekend' an adjective phrase, modifying 'any special plans'?
What is the meaning of 'for' in this sentence?
We've been through this before. Where is "for this weekend" in the sentence? After what word? What does that tell you?

And you should have looked up "for" in the dictionary website I gave you yesterday.
