• How often do you jog? Twice a week. What days do you jog? Mondays and Thursdays. (Same basic answer as Hot Licks', but more helpful.)

To determine which is correct you have to question your intention in asking the question. And yes, both can yield the same answer.

When asking "how often"...you are asking a question of frequency. Depending on the context of the question, most likely you will receive an answer including an adverbial of frequency (Src):

• always
• never
• normally e.g. "Normally twice a day."
• occasionally
• often
• rarely e.g. "Oh rarely. Maybe once a month with my friend Maria"
• seldom
• sometimes e.g. "Sometimes in the spring and summer."
• usually e.g. "I usually jog 3 times during the weekdays and rest on the weekend."

That frequency is not necessarily bound by the "days of the week". The time boundary is a determined by the responder or the context of the conversation.

When asking a question beginning with "what..." you are asking for specificity or identification . The question "What days do you jog?" has already specified 'days'. Therefore your answers should come within the context of days of the week.

e.g. I jog on Sundays, Wednesdays and Fridays

(OR as in your example:)

I jog everyday.

If you changed the context, the answer could differ. For example, say you were asking a teammate in a multi-day marathon the same question. He/She might respond, "I jog on the first and last day."
