Superman: World of Krypton Chronology Notes
During Superman: World of New Krypton Superman makes a number of appearances in other titles. However, there are not a lot of breaks in the story, making room for these appearances. Below is a list of the natural breaks in the story.
In between issue #1 and #2 there is room for appearances elsewhere as the story does not directly continue from #1 to #2.
A night passes in between issue #3, pages 13 and 14.
A week passes in between issue #7, pages 9 and 10.
In issue #9, the first panel on page 14 shows a passage of time as New Krypton is seen as going from waning to full to waning again. Since there is nothing in the story indicating the amount of time and based on the fact that Adam Strange shows up at the end of the story (an appearance that according to R.E.B.E.L.S. takes place after Blackest Night) it must be assumed that Blackest Night take place during this period.
