  • On 21st June, the summer solstice occurs in the Northern Hemisphere. This is the longest day of the year for that hemisphere.

  • The Arctic Circle, which is in the Northern Hemisphere, experiences continuous daylight throughout this day. This is because the tilt of the Earth's axis is such that the North Pole is facing towards the Sun.

  • Therefore, the Sun does not set below the horizon at the Arctic Circle on this day.
