Secular Solstice Roundup 2025

This is a thread for listing Solstice events (dates, locations, links, etc.)

If you’re not familiar with Solstice, around the darkest night of the year, rationalist communities gather to celebrate humanity’s light in the vast and uncaring cosmos. Solstice is a moment to reflect on how far we’ve come, to acknowledge the challenges that lie behind and ahead of us, and to remember that we’re not alone—that together, we can build a better future.

The ceremony typically follows the arc of the solstice itself, moving thematically from light to darkness to light again:

Light: Celebrating human achievement—the scientists, inventors, and builders who brought us from caves to civilization, who turned an indifferent universe into something livable and good.

Night: Acknowledging the struggles humanity has endured, the losses we’ve suffered, and the risks that still lie ahead. Often featuring a Moment of Darkness.

Dawn: An uplifting look at what we can accomplish if we continue the work. The light returns because we make it return.

Each Solstice features songs (often with group singing), readings, and community. While ceremonies tend to share a common structure, individual organizers bring their own themes and selections.
