Забыли поставить is после what
В вопросах о днях недели, временах года, времени и прочем глагол "to be" ставится после существительного: what time is it?/what date is it?/what day of the week is it? и так далее.
We ask WHAT DAY IS IT TODAY? to know the day of the week, and WHAT'S TODAY'S DATE? to know the number.
