Correct. It takes almost 365.25 days for the earth to make one complete revolution around the sun. The extra 0.25 day would be a bit much to handle time wise, so we stop at 365. Which leaves us a bit more shy of completing a full revolution each year after leap year. The extra day in a leap year every 4 years gets us back on track (mostly). Since the time to orbit the sun is not precisely 365.25 days, we have have the exceptions where there is no leap year to even things out.
