What time of the day ~ ?

원어민은 

What time of the day? 하루의 언제 시간 이라는 표현을 많이 쓴다. 

 

EX) One of the most important and challenging parts about volunteering is making the time to volunteer.

So as you're thinking about volunteering(벌룬티어링), really think about how much time do you have and what kind of time is that.

And this is both a question of what time during the day or during the week can you do it.
