Summer Solstice Arrives: Longest Day Dawn
21 Jun
Summary
- The summer solstice marks the astronomical start of summer.
- Earth's Northern Hemisphere tilts towards the sun during this event.
- Ancient sites like Stonehenge are central to solstice celebrations.

The summer solstice, marking the astronomical beginning of summer, occurred on June 21. This event signifies the longest day and shortest night in the Northern Hemisphere as our planet's northernmost tip tilts towards the sun. This tilt is due to Earth's axis rotating at a 23.5-degree angle.
Globally, while the Northern Hemisphere celebrates its longest daylight hours, the Southern Hemisphere observes its winter solstice. This natural phenomenon has inspired celebrations for millennia. Ancient sites such as Newgrange in Ireland and the prehistoric monument of Stonehenge in England become focal points for gatherings. Thousands congregate at Stonehenge, particularly those following Neopagan and Neo-Druid beliefs, to witness the sunrise aligned perfectly through its ancient stones.
