I've been wondering how to say 'I spent the past [time frame] [insert action]'. For example, "I spent the past hour studying Japanese". Would it be translated to something like...
日本語の勉強は最近の一時間が全かかりました
...or would it be something like...
日本語の勉強はついさっきの一時間が全かかりました。
OR! Would the sentence structure be completely different?
I'm sorry if this has already been asked before, but I can't seem to find anything concerning this type of phrasing.
