今日 (kyo) (today)
土曜日 (doyoubi) (saturday)
In some cases you can find a word that has the same kanji with different readings:
日曜日 (nichiyoubi) (sunday)
So far at my early level learning pronounciation/meaning/kana has been the way to go for me. I don't know how useful this method could be at a more advanced level.
