The summer solstice in 2025 occurs on June 20 at 10:42 p.m. EDT (which corresponds to June 21 at 02:42 UTC). It marks the longest day and shortest night of the year in the Northern Hemisphere and is considered the official start of summer. The summer solstice happens when the Earth's North Pole is tilted closest to the Sun, causing the Sun to reach its highest point in the sky at noon. At this time, the Sun is directly overhead at the Tropic of Cancer (23.5 degrees north latitude). The event is significant as it results in the longest duration of daylight for the year in the Northern Hemisphere. Conversely, in the Southern Hemisphere, this time marks the shortest day and the official start of winter. The term "solstice" comes from Latin meaning "sun stands still," referring to the apparent pause of the Sun's movement in the sky before it reverses direction. This astronomical event has been celebrated by many cultures globally with various traditional festivities and rituals. In summary:
- Date in 2025: June 20, 10:42 p.m. EDT
- It is the longest day of the year in the Northern Hemisphere
- Marks official start of summer in Northern Hemisphere
- The Sun is at its northernmost position relative to Earth
