Every 24 hours

Every 24 days
|
|
|
Every 24 days at the equator and every 35 days at the poles.

|
|
The core rotates faster then the surface.

Detailed explanation-1: -The solar rotation period is 24.47 days at the equator and almost 38 days at the poles. The average rotation is 28 days.
Detailed explanation-2: -As noted above, the sun’s surface rotates differentially, with the rotation period increasing from about 27 days at the equator to more than 35 days near the poles.
Detailed explanation-3: -The outer layers of the Sun exhibit differential rotation: at the equator the surface rotates once every 25.4 days; near the poles it’s as much as 36 days. This odd behavior is due to the fact that the Sun is not a solid body like the Earth. Similar effects are seen in the gas planets.
Detailed explanation-4: -The rotation of the Sun varies with latitude because it is composed of gaseous plasma. The rate of rotation is observed to be fastest at the equator and decreases as latitude increases.
