「日」と「日間」の違いが分かるんですが「日間」の綴り方は分かりません。

教えて頂きませんか。

（所で、「日」と「日間」の違いは「日間」の方が「日」より形式ですよね。その以外、意味が一緒です。正解ですか。）

(in case my Japanese was incomprehensible, I will translate my question to English):

I understand the difference between 「日」 and 「日間」 (「日間」 is more formal, and 「日」is less formal, but other than that the meaning is the same. Correct?). However, I am not sure how to spell/pronounce 「日間」. That is, how do I spell it in ひらがな? I have seen various versions suggestions in dictionaries, but I suppose someone who is actually Japanese would know the best.

宜しくお願い申し上げます。
