The simplest explanation I can give you is that Accounting deals with current and past transactions as they actually happened or are expected to happen. Finance is much broader and future-oriented, including all possible decisions and outcomes.
I studied Accounting in college, went on to get an MBA in Finance and Strategic Management, then became a licensed CPA. The two fields are very closely linked, and you have the ability to move between them during your career. At some point, you may decide to specialize, but experience in one is always relevant to the other.
