Kay T.さん、こんにちは！

Thank you for your question.

Yes, 1:30 for time is 一時半.

For duration, however, it is 一時間半, 半 comes after 一時間😊

Hope you enjoy learning Japanese with us:)

Sincerely,

こんにちわ！質問がありあす。

For example, I would like to say that something is going to take an hour an a half. From App. 2 I know that 1:30 is 一時半. But when I talk about the duration, when does the 間 go? Is it 一時半間? Or 一時間半?

Thanks!

Best,

Kay

質問（しつもん）ありがとうございます😄

You can say both yon-fun and yon-pun. Either one you prefer is correct👍

Though more people tend to say yon-pun because it's easier to pronounce.

Please let us know if you have any questions :)

I see translations for four minutes as both "yon-pun" and "yon-fun". I prefer yon-pun as all of the cardinal numbers ending in "p" or "n" have "pun (such as on the NHK language site), but there are as many (on a quick survey) that use "fun". I will ask some of my Japanese fiends, but thought Jpod101 would also have an answer.

Let us know if you have any questions.

Looking at the romaji: Shouldn't the "yon" be omitted for the expression for 20 minutes?
