About The Longest Day

The Longest Day is the day with the most light — the summer solstice. On June 20, thousands of participants from across the world come together to fight the darkness of Alzheimer's through an activity of their choice. Together, they use their creativity and passion to raise funds and awareness for the care, support and research efforts of the Alzheimer’s Association.
