Translation:What day is it today?
My input is "what day of the week is today?" and the system accepts. In Chinese, when you ask 今天星期幾, though there is 星期日, there can be one to six 一 to 六, and this question is widely used. If you ask what day is it, the answer of national day, new year, x'mas or any festival or public holiday or anniversary can be expected and accepted.
The hover-over hints confused me too but the comment below "what day of the week is today" helps. would a Chinese speaker also ask "what day of the month is today" (expecting an answer 1-31) and "what day of the year is today" (expecting special occasion or the full date)?
