The Sun appears to move eastward along the ecliptic relative to the stars, completing a circuit of 360 degrees in about one year. Therefore, in two months, it would move approximately 1/6 of its annual path, which is about 60 degrees. Since the celestial equator is divided into 24 hours of right ascension (RA), corresponding to 360 degrees, 60 degrees equates to about 4 hours of RA.
