the presentation day

[uktous]

Hi

Question:
Can I say “the presentation day”?

The idea I want to convey:
We aimed to complete our work before the day of which we gave the presentation.

Sentence:
We aimed to complete our work before the presentation day.

My opinion:
I googled it before. There were some examples of using it.
But I hope other people can tell me about whether I use “the presentation day” correctly.

Thanks

In fact, "the presentation day" is better and more natural English than "the day of which we gave the presentation", which is incorrect for several reasons.
