A case chronology spreadsheet turns scattered dates, records and statements into a reviewable sequence of events. The most useful chronologies do more than sort dates: they preserve the source behind each material entry.
Useful chronology fields
Consider event date, event description, people or entities involved, source, source date, verification status, related lead and notes.
Keep event date and source date separate
The date something happened can differ from the date it was reported, published or obtained. Recording both prevents later confusion.
Link every important entry to its source
A chronology is easier to review when material entries can be traced back to the document, interview or other record supporting them.
Flag conflicts instead of hiding them
If reliable sources disagree, preserve the conflict and create follow-up rather than forcing one version into the timeline.
