International Day of the Celebration of the Solstice
June 21 · Level 10 · #150 of 2238

The International Day of the Celebration of the Solstice honours traditions shaped by the Sun and the changing seasons. This UN observance recognises how watching the sky has helped communities organise calendars, farming and shared celebrations for centuries.
How it is celebrated: gatherings include sunrise watching, folk festivals, music and cultural events. Bonfires, dancing and time outdoors feature in different seasonal traditions.
The June solstice happens at one astronomical instant for the whole planet. Yet it marks the beginning of astronomical summer in the Northern Hemisphere and winter in the Southern Hemisphere.
