Comments for 五

I know katakana and hiragana pretty well but just starting kanji..  Which I'm sure will be a lot harder.

It says you can write it in alternative forms, like いつ  which is how I saw it used for "the fifth month" writting in katakana as いつか (and in kanji as 五日) but why does the audio for the いつ  form still sound the same: "go"?  Shouldn't it sound like "itsu" in this case?  So いつか should sound like "itsuka".

Thanks tons

I just asked a friend who's spent a lot of time in japan, and he said it's probably just a broken website.

I understand the "5 minutes part", but was the 100 buried alive churchgoers really necessary?
