Explanation
During LEU's early Wave One movies, it was expected to use real time, with the movies giving references and Easter eggs to each other without giving specific years, albeit with clear indications that they occurred in their release years. The Lego Movie was set "eight and a half years after Finn was born" in 2014 and about three years before The Lego Batman Movie, which takes place in 2017, thanks to comments made by Alfed and Batman. The Lego Ninjago Movie is also set. in that year. The Billion Brick Race explicitly takes place shortly before The Lego Movie due to its post-credits scene that runs parallel to the film's final battle, which is a "month after" the main events seen in The Billion Brick Race. The Lego Movie 2: The Second Part is set five years after the events of The Lego Movie and The Lego Dimensions Movie is firmly established in 2022.

Linear history writers wanted the Wave Two movies to continue to be set in real time, mentioning dates and putting years on screen, relating to the events of The Lego Dimensions Movie: The Lego Movie 3 takes place "two years" later, in April, 2024; The Lego Batman Movie: Villains takes place three years later and you can see how the reconstruction of downtown Metropolis is still continuing; The Lego Chima Movie is set before that chronologically, but it takes place in its dimensions in the 6th Millennium, in the year 5050. Ninjago - The Movie takes place almost ten years after the 2017 movie, but being an independent sequel and soft reboot it is almost autonomous. The Lego Harry Potter Movie takes place in the 90s, but it happens chronologically nine months after Ninjago - The Movie, and only one year before Episode I that together with Episode II take place throughout 2028 with the final scenes in early 2029. With both Monkie Kit and the Born of a Hero and Wyldstyle set earlier in the timeline; the latter set in mid-2013.

The series produced have interconnectivity with feature films, with the first season of Girls Rule setting a month after the events of The Lego Dimensions Movie, and setting directly with The Lego Batman Movie: Villains in season five; Lord and Rings is set in real time since The Lego Movie 3, positioning it more specifically at the end of 2026 and extends until the beginning of 2028 where it is related to The Lego Dimensions Movie: Episode I. The first season of City Undercover begins in the middle of 2013 and in the book "LEGO Extended Universe Ultimate Timeline" it is specified that it begins immediately after Wyldstyle in June 2013, in addition, during its fourth season an allusion is made to the events of The Billion Brick Race, confirming the exact dates of several of some movies, such as The Billion Brick Race in January 2014, The Lego Movie in February 2014, The Lego Movie 2: The Second Part in February 2019, and The Lego Batman Movie in May 2017.

Harley Quinn and Joker takes place roughly nine years before The Lego Batman Movie and "Ninjago Histories" begins in its first chapter just after the first movie in 2017.

Universe
Dan Lin, Phill Lord, and Christopher Miller have at times confirmed that the various dimensions are connected and do not function as parallel timelines, which only exist within the same dimensions, as depicted, in The Lego Movie 2: The Second Part or The Lego Batman Movie: Villains, where there are different versions of the existing characters in the dimensions, encapsulated in their own timeline that may or may not be connected to the main one.

The three bases of the LEGO "Multiverse" are  Reality ,  Space  and Soul. It has also been said that they are all connected in spaces such as the Phantom Zone, where different villains of the existing dimensions are housed, the Void or the Ethereal Divide (which is the cause of the creation of vortices and automatic teleportation through these, differentiating themselves from his television version) also, as shown in Ninjago - The Movie, the dimensions work somewhat similar as the 16 kingdoms captured in the television series.

The "Dimensions" of The Lego Movie are just spaces that coexist in one., but "Ninjago Dimension" is directly connected, which is why LLoyd is considered as a master builder directly, even if it is not the same design of the 2017 film. Chima is directly connected to Ninjago through Ethereal Divide as shown in the series. It is alluded that the dimension of Nexo Knights and other themes also exists, but they do not expect to see it on screen.

Phill Lord stated that time passes differently in all dimensions, which explains why in Chima they are in the year 5050, of the sixth millennium, while most spend "in real time" with the "real world" of the humans, or "Magic Dimension" is found in the 90s.

Fundation Prime is the center of the universes and although it connects directly to the rest of the state of a place similar to outer space, it is not the same as the one seen in The Lego Movie 2: The Secod Part, also, Systar System was not a dimension other than Dimension Prime, if not an extension of it.

According to David Yate, The Lego Harry Potter Movie is based on a "second and alternate timeline" of the Wizarding World, where different events occur and Voldemort has not yet been defeated. The "first timeline" is an identical one shown in the Life Action movies, and it is even alluded to being the one seen in the LEGO Harry Potter video games, which is why Voldemort is in the Phantom Zone in The Lego Batman Movie, set in 2017, even though Harry Potter did not enter Hogwarts in the 1980s.

It is possible that large-scale destructive events in one dimension directly affect others such as; The Lego Movie's final battle at L City; or the Crime Syndicate Campaign to the Magic World.

Dan Lin, in an interview in 2027, has said that, in reality, "all the themes produced by LEGO, in sets, books and video games exist in the Multiverse" although this has been contradicted in some occasions. Regardless, Benny, in The Lego Dimensions Movie: Episode I, says that probably the existence of more unknown dimensions is almost infinite, and the explored part is minuscule.

If Lord Vortech had fused all dimensions into one, the "reality" and "space" of the Muliverse would probably have disappeared, but his actions unleashed "The Soul" anyway.
