From TARDIS Index File, the free Doctor Who reference.

New Year's Eve was another name by which 31st December was known. As the last day of the year — at least according to some Earth calendars — it was often a time for celebrations and parties, generally centered around midnight, when the last few seconds of a year could be experienced. Though the parties which occurred on this date were often raucous, some individuals might have marked the occasion with a somber reflection on the passage of time.

Notable New Year's Eves included:

• 1930: The Doctor finally brought Charley Pollard to the Raffles Hotel in Singapore, but an old enemy of the Doctor soon forced them to leave for a whirlwind tour of history. (BFA: Seasons of Fear)
• 1965: Chasing the Daleks, the First Doctor briefly materialized his TARDIS in Trafalgar Square during the New Year's Eve celebrations. (DW: The Daleks' Master Plan)
• 1986: Ben and Polly reunited long after their travels with the Doctor had ended. They reflected on the nature of their failed relationship, and their lives with different partners. (ST: Mondas Passing)
• 1999: The Seventh Doctor regenerated when he was accidentally killed by the staff of Walker General Hospital in San Francisco, and then prevented the Master from using the TARDIS to destroy the universe. (DW: Doctor Who) At the same time Iris Wildthyme faced a different threat in San Francisco. (BFIW: The Panda Invasion) The Sixth Doctor and Mel were twice in England on New Year's Eve of this year. Once they stopped an attack by the Great Intelligence, (MA: Millennial Rites) and on another occasion they prevented an attack by the Nestene Consciousness. (DWM: Plastic Millennium) Meanwhile, in Cardiff, Jack Harkness assumed leadership of Torchwood Three, following a tragedy involving the previous leader. (TW: Fragments)
• 2004: Rose Tyler missed a New Year's Eve party, thereby allowing her to unwittingly meet the regenerating Tenth Doctor, prior to the instance when she first encountered the Ninth Doctor. (DW: The End of Time)

New Year's Eve

Memory Beta, the wiki for licensed Star Trek content.

New Year's Day was a human holiday celebrated annually on January 1, commemorating the beginning of a new calendar year. These celebrations were normally combined with those of New Year's Eve, celebrating the end of the previous year on December 31. One of the largest traditional celebrations was held in Times Square in New York City.

Q while visiting New York City, briefly befriended a human woman in anticipation for New Year's of Jan. 1st, 2000. Unbeknownst to everyone else but himself the ball that is dropped to usher in the new millenium was sabotaged by terrorists. It kills all in attendance, except for Q. He then leaves pondering how blissfully ignorant mortals are to their concepts of importance verses the greater universe. (TNG novel: I, Q)

The crew of the Enterprise celebrated New Year's Day in 2152. (ENT novel: What Price Honor?)

Celebration of New Year's Day in 2367 was muted, as Earth was under a blackout, due to the threat from the Borg. (SNW short story: "Final Entry")

San Francisco celebrated New Year's Day 2378 with a long congratulations to the USS Voyager and its crew, following their recent return from the Delta Quadrant. (VOY episode: "Endgame"; VOY novel: Homecoming; SNW short story: "Uninvited Admirals")

In an alternate timeline, Trip Tucker and T'Pol attended the celebration in Times Square for the beginning of New Year 2200. A violent confrontation broke out at that event, and Tucker was tragically killed. (Star Trek: Myriad Universes novel: A Less Perfect Union)

From Muppet Wiki

New Year's Eve occurs every December 31, and is considered the final day of the year, followed by New Year's Day on January 1. However, in America, New Year's Eve is generally deemed more important, a night of revelry, consumption, noise-making, singing "Auld Lang Syne," and watching Dick Clark (or, in recent years, Carson Daly).

Generally a lesser holiday in the Muppet pantheon, it did receive its due in 1993, with the special Sesame Street Stays Up Late and its tie-in book. (The special was released on home video as Sesame Street Celebrates Around the World.)

In 1996, Miss Piggy served as a special New Year's Eve correspondent on Jay Leno's The Tonight Show. Piggy stood on the roof of the Mariott Marquis Hotel at Times Square, New York City, freezing her bazongas off while wearing a low-cut sequined gown. ("With the wind-chill factor, it's sixty-eight degrees below zero!" she complained.) She blamed Bernie for the situation, since instead of spending a romantic candlelight dinner with Kermit, she's stuck on top of a building with three teamsters named Vinnie. She grew more satisfied as the evening wore on, however, excitedly watching as the ball prepares to drop, and dancing on the rooftop to ring in the New Year.

A year later, Miss Piggy appeared on The Today Show on New Year's Day, 1998, following a New Year's date with Matt Lauer. Piggy complained about being up so early, and said that she only agreed to appear on the show so she could break things off with him. As an explanation, Piggy said, "Can we just say that when a person picks up a pig for a date, that the New Year's kiss does not begin at 6:30pm?" Lauer accepted the breakup somewhat gracefully, although he asked her to keep an open mind about a date for next New Year's. He ended the segment by kissing her on the nose and hugging her.

Grover (and Super Grover) appear on The Sunny Side Up Show to help Kelly and Chica celebrate the coming of 2009 on New Year's Eve and New Year's Day. The trio sing a song about their New Year's resolutions to the tune of "Turkey in the Straw." Super Grover's include learning to take pictures, tieing his shoes, discovering a new breed of blue apple, hugging a penguin, and drinking hot chocolate with a dove.
