Hi guys!

I figured some of you guys speak japanese and might be able to help me out with my assignment.


In short, I need to figure out which interrogative words to write in each blank space in the following sentence. (1 interrogative word per blank space)

Q : ハロウィーンは(___)(___)ですか。
A : 10月31日です。


I was thinking at first to put "何日", but I guess that would count as one interrogative word and can't figure out what the other word would be.

Anyone cares to help me out? Thank you! Will +rep.
