I'm aware that 日和 can be used with weather conditions to show that it's a good day for something.
Today's the perfect day for a picnic.
But can you use it for non-weather related situations? If I wanted to express that a given book is a great book to study Japanese with (it has an interesting story, plus good vocab and furigana for instance) could I say:
That book is perfect for studying Japanese.
goo辞書 lists a possible definition as 「物事の成り行き。雲行き。形勢。」, so I thought maybe so. Or is there a more natural way to express this?
