Latest sunsets follow the summer solstice
- The latest sunsets occur after the summer solstice because the day is more than 24 hours long at this time of the year.
- For the Northern Hemisphere, the latest sunsets and evening twilights are happening around late June and early July, with varying dates depending on the latitude.
- In the Northern Hemisphere, the longest day falls on the June solstice, with the latest sunsets around June 27 at 40 degrees north latitude and later dates farther north or south.
- In the Southern Hemisphere, the latest sunrises of the year occur in late June and early July.
- Clock time and sun time do not always align due to Earth's tilted axis and varying distance from the sun throughout the year.
- There are three types of twilight: civil, nautical, and astronomical, each defined by the sun's position below the horizon.
- North of 50 degrees north latitude, there is no true night in June, leading to phenomena like midnight twilight and the midnight sun.
- The discrepancy between solar time and clock time explains why the latest sunsets do not coincide with the longest day of the year.
- Mid-northern latitudes always experience the latest sunsets in late June due to the Earth's positioning in relation to the sun.
