When to use did vs does?

The difference between did vs does is:

Does is simple present tense: He does his schoolwork once he gets home from school.

Did is the simple past tense: He did his homework when he got home from school.

Did and does refer to different points in time: does is present; did is past. This is not the only difference between did and does: does is only used in the third person singular case. Do (present simple) and did (past simple) are used for all other subjects, be it singular or plural.

When to use did vs done?

We’ve covered that the simple past tense of ‘do‘ is did. We also know that does is simple present, and only used in the third person singular. That leaves the past participle, done (rhymes with won). When is it correct to use did vs done?  This is a question on the distinction between the past tense vs the past participle. To see the difference in their use, compare these sentences:

He did a lot of homework today. (simple past)

He has done a lot of homework today. (past participle)

The second sentence places the helping verb, has, written in italics. That’s to highlight the importance of the role of has in this sentence—try removing ‘has‘, and see what turns out:

He done a lot of homework today.

This is incorrect English, and is not a proper sentence or thought. Without helping verbs, participles cannot stand alone as a fully-functioning verb and part of speech. Participles are forms of verbs, and they participate in various aspects of speech: they act like adjectives by modifying nouns, and pair with auxiliary verbs to show tense, subject, count and so on. Importantly, ‘done‘ and other participles cannot, on their own, reflect tense, and so, they require helping verbs:  had/have, should, would, could, and so forth.
