About Chester Greenwood Day

Chester Greenwood Day is a Maine commemorative day observed on 21 December each year in honor of Farmington inventor Chester Greenwood.

Maine law requires the governor to issue an annual proclamation inviting people in the state to observe the day with appropriate ceremony and activity.

Why Chester Greenwood Day matters

The day recognizes Greenwood’s inventive work and his place in Maine history, especially his association with patented ear-mufflers.

The statutory December 21 observance is distinct from Farmington’s community celebration, which the Maine State Museum describes as taking place on the first Saturday in December.

History of Chester Greenwood Day

Maine Revised Statutes Title 1, section 117 designates December 21 of each year as Chester Greenwood Day.

The statute’s section history traces the designation to Public Law 1977, chapter 262.

Maine’s governor continues to issue annual proclamations; the 2025 proclamation again designated December 21 as Chester Greenwood Day.

The Maine State Museum describes Greenwood’s patented ear-protector work and separately notes Farmington’s annual first-Saturday-in-December community celebration.
