Marmot Day is an Alaskan holiday established to celebrate marmots and Alaskan culture. Although local festivals have been part and parcel of frontier life for decades, Marmot Day became an official holiday on April 18, 2009, when the 26th Alaska State Legislature officially passed Senate Bill 58.^[1] Marmot Day is celebrated on February 2, replacing Groundhog Day with a holiday honoring Alaska's marmots. From Juneau^[2] to Anchorage^[3] to Fairbanks,^[4] and all the cities in between, Marmot Day has become an Alaskan institution.

Senate Bill 58, sponsored by Sen. Linda Menard, R-Wasilla, was first introduced by the late Dr. Curtis Menard, Linda Menard's husband and former state legislator. Concerned by the gradual decline of Alaska's folk values, Dr. Menard proposed his idea of creating Marmot Day in the 1990s. After getting stuck in a committee, the controversial Marmot Day bill died in the legislature. Sen. Linda Menard reintroduced the bill for the 26th Alaska Legislature, and the bill passed on the second to last day of the legislative session, and Sarah Palin signed it into law.^[5] As Senator Menard said, "By recognizing the marmot, our state [built] a tradition and legacy to be built on for future generations.^[6] It has become tradition to eat French Onion Soup on Marmot Day in some parts of Alaska.^[7]

Marmot Day is also the name of a community celebration in Owosso, Michigan, occurring on July 25 (or on the following Monday if the 25th falls on a weekend).^[8] It is a celebration of all marmots, which include groundhogs, woodchucks, and ground squirrels.

Marmot Day was first celebrated in 2002 as a day celebrating all marmots. A luncheon is traditional as part of the celebration, marmot jokes and ginger snaps are shared, among other festivities typical of party celebrations.^{[9] [10]} In recent years the celebration has been held at the Covenant Eyes global headquarters in Shiawassee County.^{[11] [12]} At 12:45 P.M., a marmot is positioned outside its hole, and if it goes into its hole, legend has it that summer is over; if it does not go into its hole, there will be one more month of summer.^{[13] [14]}
