Notes: The solstice refers to the events when the Sun’s apparent position in sky reaches its northernmost or southernmost extremes. Solstice happens twice a year, and twice a year happen the equinoxes. Altogether, the four are considered to start 4 seasons.
At the time of northern solstice, sun is perceived to be directly overhead the 23.44° north known as Tropic of Cancer.
Likewise, at the southern solstice the same thing happens for latitude 23.44° south, known as the Tropic of Capricorn.
