A chronology is not a diary and it is not an argument disguised as a table. Its purpose is to help another person understand what happened, in what order, and which source supports each entry.
Begin with the decision ahead
Write one sentence explaining why the record is needed: “I am preparing for the meeting about my changed duties on 20 May.” That sentence is a filter. An unrelated disagreement from two years ago may feel important but still have no place in this version.
Create four columns: date and time, event, source, and unresolved point. Use the exact date on a letter or email. For a remembered conversation, write “approximately” and identify who was present. Never make a remembered date look documented.
Use neutral verbs
“Sent,” “asked,” “declined,” “assigned” and “received” are easier to verify than “attacked,” “ignored” or “punished.” You can record impact separately: “I understood this as replacing my previous responsibility; written confirmation was not provided.”
Keep original files. A chronology points to evidence; it does not replace it. Give each source a simple label such as E03 for an email or N02 for a contemporaneous note.
Mark gaps instead of filling them
If a manager refers to “several earlier conversations” and you can identify only one, record that difference. Do not invent certainty in either direction. A well-marked gap often produces the most useful question for the next meeting.
Finally, remove duplicates and check whether every row advances the stated purpose. A six-event sequence that can be read in five minutes is often more useful than sixty pages placed in date order.
