29th century
The 29th century was defined in the calendar of Earth as being from 2801 until 2900.

Events 

 The Federation timeships Aeon and  operate in this timeframe. ()
 The Na'kuhl, a faction in the Temporal Cold War opposed to the Temporal Accord, escape from the Temporal War by using one-way stealth time travel to go to an Earth in the early 1940s in an alternate timeline in which the Temporal Cold War became the Temporal War. In this alternate past, Vosk, with the help of the Nazi Party, constructs a temporal conduit and returns to this century, igniting the Temporal War they escaped in the first place. All damage this war causes to the timeline, including the events which allowed Vosk to build his conduit and the Nazi's invasion of the US, is reversed when the conduit is destroyed before the Na'kuhl reach this century.

 (circa)
 It was estimated that the Kelvans' response to the Federation's message would be received in this year. ()

 (circa)
 In an alternate timeline, Henry Starling, having acquired the timeship Aeon in 1967, travels to Earth in this time from 1996. His inexperience with the technology results in a temporal explosion that destroys the Sol system. The explosion is witnessed by Captain Braxton aboard another version of the starship Aeon from earlier in its timeline. Braxton detects debris from the secondary hull of  following the explosion, leading him to believe that Voyager is responsible for the explosion, and travels to the Delta Quadrant in 2373 in order to stop the incident by destroying Voyager. ()  

Before 
 The time ship Relativity, under the command of Captain Braxton, uses its temporal sensors to scan the USS Voyager in 2375 and finds a temporal explosion during that period. The crew recruits Seven of Nine three times to find out how, where, and by whom the explosive device was planted. When Braxton himself is revealed to be the saboteur, Captain Kathryn Janeway is sent back in time to apprehend him just as he arrives on board. Seven and Janeway are returned to their time frame and the three Braxtons, one from the ship, one from when he was planting the device, and the one from when he arrived to activate the device, are reintegrated and later stand trial.
