Ahh, thanks for that. Should have realized that the sun doesn't have a "fixed" surface. It seems that the center, however, has a rotational frequency of about 432nHz which results in a rotation period of 26.8 days. All of these numbers are way faster than I imagined, which means that the length of the "solar year" is still incredibly long in "solar days".
