The phrase "Groundhog Day" has entered common usage as a reference to an unpleasant situation that continually repeats. Goldberg paraphrased the common meaning as "same stuff, different day".
In the military, referring to unpleasant, unchanging, repetitive situations as "Groundhog Day" became widespread soon after the movie's release in February 1993. A magazine article about the aircraft carrier USS America mentions its use by sailors in September 1993. The film was a favorite among the Rangers deployed for Operation Gothic Serpent in Somalia in 1993, because they saw the film as a metaphor of their own situation, waiting monotonous long days between raids. In February 1994, crew members of the aircraft carrier USS Saratoga referred to their deployment in the Adriatic Sea, in support of Bosnia operations, as Groundhog Station. A speech by President Clinton in January 1996 specifically referred to the movie and the use of the phrase by military personnel in Bosnia. Fourteen years after the movie's release, "Groundhog Day" was noted as common American military slang for any day of a tour of duty in Iraq, often as a successor to the World War II-era slang term "SNAFU" ("Situation Normal: All Fucked Up").
In his Iraq War memoir Victory Denied, MAJ Roger Aeschliman describes guarding assorted visiting dignitaries as his "Groundhog Day":
The dignitary changes but everything else is exactly the same. The same airplanes drop them off at the same places. The same helicopters take us to the same meetings with the same presenters covering the same topics using the same slides. We visit the same troops at the same mess halls and send them away from the same airport pads to find our own way home late at night. Over and over and over and over and over and over and over and over and over until we are redeemed and allowed to go home to Kansas. Amen.
Member of Parliament Dennis Skinner compared British Prime Minister Tony Blair's treatment following the 2004 Hutton Inquiry to the film. "[The affair] was, he said, like Groundhog Day, with the prime minister's critics demanding one inquiry, then another inquiry, then another inquiry." Blair responded, "I could not have put it better myself. Indeed I did not put it better myself."
In 2004, Italian film director Giulio Manfredonia shot a remake of Groundhog Day under the title of È già ieri (It's Yesterday Already). The movie features a mixed cast of Italian and Spanish actors and actresses and is about an egocentric TV documentarian (Antonio Albanese) who finds himself trapped in a time loop during a reportage he is taking in Tenerife.
In the 2015 memoir, Guantánamo Diary, Mohamedou Ould Slahi refers to the film twice to describe his ongoing confinement in Guantanamo, Cuba.
On February 2, 2016, fans of the film in Liverpool experienced their own "Groundhog Day" by binge-watching the film 12 times in 24 hours.
