↑Series producer Greg Weisman stated that even though the series does not have a "canon year", the production team based the days of the week on the 2010 calendar. He has also revealed that Zatara and Superman started their crime-fighting careers in 1998 and Zatara was 40 in 2010. In "Og Htrof Dna Reuqnoc!", Zatara says he was 28 years old when he first heard of Superman and was inspired to start fighting crime, which adds up to the aforementioned debut year and character age.
