The film has a tagline "First film of the year" because it was released on January 1, 2006 (the premiere took place at 3 a.m. in a Moscow theatre of "Oktyabr").
When Kostya's father, played by Valeriy Zolotukhin, arrives at Yegor's party, he is greeted by Anton "Valeri Sergeyevich". "Valeri Sergeyevich" is Zolotukhin's real name.
The original movie title was "Nochnoy dozor 2: Mel Sudby" (Night Watch 2: The Chalk of Fate), as the movie is based on two stories from Sergey Lukyanenko's book "Night Watch". A teaser trailer with the title "Nochnoy dozor 2" could be seen on the Russian DVD of Turetskiy gambit. A few months before release, the title was changed to "Dnevnoy dozor" (Day Watch). The end credits reflect the title change to "Dnevnoy dozor", though they keep the subtitle "Mel Sudby".
At the celebration of Yegor's birthday, many Russian celebrities are present, among others: artist Nikas Safronov, music critic Artemiy Troitskiy, producer Yuri Ayzenshpis, leader of the band "Leningrad" Sergey Shnurov and singer Boris Moiseev.
When Anton picks Svetlana up from her school classes for Light Others, several Russian Sci-Fi writers can be seen as students: Sergey Lukyanenko (author of the "Watch" novels), Vladimir Vasilyev (co-author of the novel "Day Watch"), Oleg Divov and Eduard Gevorkyan.
The clips of the soccer match featured in the film were taken from a friendly match of national teams: Russia 4-3 Lithuania (the match took place on 18 August 2004).
The scene in Moscow subway was actually filmed at the Saint-Petersburg subway station "Politekhnicheskaya". It was shot late at night when the station was closed.
