A sentence grammar question

[Gabriel729843]

Hello! I found in my exercises in "Invite 2" a sentence like 上个星期五我没有出去 and it mans "I didn't go out last friday". Why is there 没有 and not 不, if 没有means "don't have"?

[Semeltin]

This is the common way to negate in the past tense.
(不 doesn't imply that it happened in the past)

You can also leave out 有. 没 is the short form of 没有.

To my knowledge 没 is used to negate sentences in the past tense instead of 不.

Thank you very much Semeltin and Celica!
