Before you start
The Sun follows a different track across the sky each day of the year. Summer paths are higher and longer.
Key idea
Earth's 23.5° tilt changes the Sun's declination through the year, which changes rise direction, maximum height, and day length.

Why it matters in Hong Kong
Hong Kong's subtropical latitude means the noon Sun can pass slightly north of zenith in summer.
