"Han klarte det for første gang på tirsdag."

Translation: He was able to do it for the first time on Tuesday.

the pronunciation of "det" in the normal speed version is very odd

Why is "that" not accepted as an alternative? I used "He managed that for the first time on Thursday." and it was not accepted.

Haha because I said Thursday. When I use Tuesday, "that" is accepted. LOL
