How long does it take to rotate • Congratulations! Your basic calculations are correct: the Sun does rotate every 27 days at its middle, about where the spots we observed appeared. Note: The Sun, being a gaseous body - not a solid object - does not rotate at the same speed all over its surface: thus, it rotates about every 35 days near its poles.
