How do I tell whether a passage is in chronological order?
Quick answer
List events in the order the passage presents them, then arrange those same events by when they happen. If the lists match, the passage is told in chronological order. If the narration presents a later event before an earlier one, it shifts in time, as in a flashback. Use the events and their relationships—not just time words—to decide, and mark unclear timing as uncertain.
The question, the details, the next step.
A practical checklist
Label each distinct event in the order the passage presents it.
Use time clues and event relationships to place the same events on a timeline.
Compare narrated order with event order and name any shift.
Mark unclear timing as uncertain rather than guessing.
A few more useful answers
Does one flashback mean the whole passage is out of chronological order?
It means the passage is not strictly chronological at that point. You can describe the overall pattern more precisely, such as “mostly chronological with one brief flashback.”
Is a sentence about something earlier always a flashback?
Not necessarily. It may provide brief background rather than present an earlier scene. Identify when the event happened and where the passage tells about it, then compare the two orders.
What should I do if I cannot tell when an event happened?
Mark its timing as uncertain and avoid guessing. You can still compare events whose order is clear, but qualify your conclusion if the text leaves part of the timeline unresolved.
