Martin Z. Mollusk Day is observed on the first Friday of May. In 2026, it falls on May 9. This whimsical holiday serves as Ocean City, New Jersey’s unique version of Groundhog Day, featuring a hermit crab mascot who predicts the arrival of summer. If the crustacean sees his shadow, local tradition dictates that summer will arrive one week early for the coastal community.

History of Martin Z. Mollusk Day
The tradition began in 1974 when Mark Soifer, the long-time public relations director for Ocean City, created the event as a creative way to promote the town before the busy summer season. Soifer was known for inventing quirky events to give the “America’s Greatest Family Resort” a distinct personality. He introduced Martin Z. Mollusk, a giant hermit crab, as the official weather prognosticator to build excitement among residents and tourists during the spring.
Since its inception, the ceremony has become a centerpiece of the city’s spring calendar. The event has reached over 50 years of consecutive celebrations, with Martin consistently delivering “good news” to the crowds gathered on the beach. While the original Martin has long since retired, the mantle is passed down to successor hermit crabs who continue the tradition of seeking their shadows under the watchful eyes of city officials and local meteorologists.

It acts as an official “herald” for the season, incentivizing early-season visitor traffic and helping businesses finalize staffing before the Memorial Day rush. The event creates a sense of momentum for the community, turning collective attention toward the upcoming months of sun and tourism.
Beyond its economic impact, the day reinforces the family-friendly branding of the Jersey Shore.

The predictability of the celebration—always focusing on the arrival of summer—provides a positive and humorous start to the coastal peak season regardless of the actual weather conditions on the day of the ceremony.
