Well, at its equator the Sun rotates in roughly 25 days and at the poles 32 days or thereabouts.

Sunspots cycle over a roughly 11.2 year period and their occurrence over that time depends on how active (or not) the Sun is at the time.

You can see them whenever they're visible on the Sun's surface, some last days others for months.
