Noortevahelisi

Noortevahelisi refers to a phenomenon observed in the Northern Hemisphere, particularly in regions near the Arctic Circle, where the sun does not set for a continuous period during the summer months. This occurs due to the Earth's axial tilt, which causes the sun to remain above the horizon for 24 hours at a time. The term "noortevahelisi" is derived from the Estonian language, where "noorte" means north and "vahelisi" refers to the period between sunrise and sunset.

The exact duration and timing of noortevahelisi can vary depending on the specific latitude and longitude of the observation point. Typically, it begins around the summer solstice, which occurs on or around June 21st, and ends around the autumnal equinox, which falls on or around September 22nd. During this period, the sun's path across the sky is at its highest, resulting in long days with minimal variation in daylight hours.

Noortevahelisi has significant cultural and ecological implications. Culturally, it has been celebrated in various ways, including festivals and rituals that honor the sun and its influence on the environment. Ecologically, the extended period of daylight promotes plant growth and supports the biodiversity of Arctic regions. The phenomenon also has practical implications for human activities, such as agriculture and navigation, which are adapted to the unique conditions of noortevahelisi.
