Ninth day or day nine. No matter how you look at this word, it makes a lot of sense.
Words that count days use an exceptional reading. Even though this is a jukugo word, it uses kun'yomi readings for both of the kanji. You learned this reading for 九 when you learned 九つ, so you should be able to read this one too!
