Celebrating the Summer Solstice: Traditions and Scientific Marvels

From ancient rituals to astronomical observations, the longest day of the year holds rich cultural and scientific significance.

The summer solstice in 2024 occurs on June 20 at 4:50 PM EDT, marking the start of summer in the Northern Hemisphere.
Historically, solstices have been celebrated with various rituals, including bonfires and communal gatherings.
In tropical regions, 'zero shadow' days occur around the solstice, where objects cast minimal shadows at solar noon.
Ancient astronomer Eratosthenes used solstice shadows to estimate Earth's circumference over 2,000 years ago.
Modern celebrations include outdoor activities, feasts, and sun salutations in honor of the sun's peak.
