that/when

[SARDORBEK]

Hello, dear ALAN!
I,together with my friends - fans of this club, have a lot of questions.
If YOU would answer all of them, we would be very happy.

Question № 1

1) The last time that I heard from Madonna was when she called me last week.
2) The last time that I saw her, she looked fine.
3) I haven’t seen them since the year that they got married.

Instead of “that”, can I use “when” in the three sentences above?

Thank you…

[Alan]

No, you cannot!
