have and had (Did you have/had a good day?)

[Imalaski]

Which is correct, Did you have a good day? or Did you had a good day.

Hi,

It must be 'have'. In questions we use 'do' 'does' or 'did' + the infinitive of the main verb for present and past tenses as in:

Do you understand what he is sayng?

Did you understand what he said?

In you sentences 'have' is used to suggest 'experience'
