This is a sentence from a person's regret about being born. The sentence is:
"Not a week goes by THAT I don’t wish I was never born."
I understand the sentence, but I am not quite sure about the grammar. The word "THAT" is describing the word "a WEEK", so the word "THAT" is functioning as a relative pronoun.
Since he regrets about this life every week, the regret is experienced in or during every week, which requires a relative pronoun "WHEN", not "THAT", doesn't it?
So, my question is, should the sentence have been as follows:
"Not a week goes by WHEN I don’t wish I was never born."
