May 18, 2026 — Today is Visit Your Relatives Day, a reminder of how connections build over time.

Today we’re looking at moments defined by timing.

From the sudden eruption of Mount St. Helens in 1980, to the long-term success of early heart-lung transplants in 1987, to the Seinfeld finale in 1998, which became a shared experience for millions.

Plus, a look at Rick Wakeman, whose layered musical style helped shape progressive rock.

It raises a question about how timing—whether sudden or sustained—shapes how something is remembered.

Anyway… that’s what I ended up finding while working through May 18.
