what time 是问的具体时间，例如：what time do you get up? what time is it? 回答就是直接说什么时间就行，例如： I get up at 6 o'clock. It's 7:30 now. how often 问的是频率，就像 how often do you eat out? 回答时要用一些频度副词，就像usually, always等， 也可以用 three times a week, twice one day等。例如，I eat out three times one week. 但这里要注意一下对划线部分提问的情况，例句： I go to see my grandpa four times a month. 如果划线部分是整个“four times a month”的话，就要用“how often”提问，因为这是问的频率。如果划的只是“four times”，没有后面的“a month”，那就得用how many times a month do you...来回答，因为这样问的是次数，不是频率。
what time问的是具体时间：例如：你每天早上几点吃饭？What time do you have lunch every morning？回答：7：00 how often是对频度副词提问：例如：你多久换一次眼镜？How often do you change your glasses?回答：1year

What time是只比较具体的时间，而how often是指频率。 例如：What time do you go to school? 答：I go to school on 7:25.
How often do you go to school? I usually go to school from Monday to Friday.
