In reality, it is due to the 23-degree tilt of the Earth’s axis that the Sun appears above the horizon for different lengths of time at different seasons. Class schedule available, Monday, February 1 Semester Length Classes. Its often called the longest day of the year because its the day with the most daylight (every 'day' has 24 hours). Some people believe that our seasons are caused by the Earth’s changing distance from the Sun. The first day of summer 2021 is June 20 at 11:32 p.m. Many pagan traditions and rituals claim this day with the vivid celebrations that involve bonfires and meadow dances.
This phenomenon is most noticeable at the Arctic Circle where the Sun hugs the horizon for a continuous 24 hours, thus the term “Land of the Midnight Sun.” Here’s how it differs from an equinox. The Summer Solstice Day, or the day when the sun stays for the longest in the sky, is considered the first day of summer. At the solstice, the angle between the Sun’s rays and the plane of the Earth’s equator (called declination) appears to stand still. The term “solstice” comes from the Latin words sol (sun) and sistere (to stand still). The first day of summer 2021 arrives in the United States on Sunday, June 20, officially starting at 11:32 p.m. The summer solstice can occur anywhere between June 20-22.

This is the June solstice (usually 20 or 21 June) in the Northern hemisphere and the December solstice (usually 21. The timing of the summer solstice is not based on a specific calendar date or time. The summer solstice occurs during summer. Why Isn’t Summer on the Same Date Every Year? The solstice happens at the same moment for everyone, everywhere on Earth. For those who live in the Southern Hemisphere, this was the shortest day of the year and the arrival of winter.
