Translation:Which day of January is the show date?
Aloha! It seems it is not the only answer. I have used the translation from the word bank, and it was accepted.
So, there are at least two translations here:
Which day of January is the show?
What day in January is the show?
Are not these sentences meaning the same? Since I am not a native English speaker, I think I cannot be sure about which sentence in English is better. It seems that both sentences work in this exercise. :)
