[Grammar] Present perfect tense

[Gilles L]

Dear teacher,
Am I right in assuming the present perfet relates to an action that is completed but the period of time referred to has not yet elapsed ?

For example, if I were to say:

I have have dance with my teacher today
Does this sentence correctly infers that I am no longer dancing while the day is not over yet ? as opposed to

I danced with my teacher yesterday. Meaning that I am no longer dancing and the period referred to is also finished.

Thank you

Yes, that's what they mean, but it's "I have danced with my teacher today" not "I have have dance..."; which doesn't mean anything.

Yes, but if you said "I danced with my teacher today" it would still have the same meaning. You danced at some point today, and today is not over yet.

I have eaten too much today.
I ate too much today.

To me, they mean the same.
