Reconcile conflicting dates
See this course’s project requirements
A six-part community-history packet with a bounded question, finding-aid path, record analysis, timeline, citation and rights notes, and a 150–250-word evidence-based account.
Keep your working files in your own notebook or software. Save a private description, checklist, and work link in My Proof.
What to include
- State a bounded question and a search plan that could challenge the starting caption.
- Trace R3 through the correct collection and item locator.
- Analyze record purpose and shared evidence before drawing conclusions.
- Create a timeline that separates approval, event, publication, and later annotation.
- Attach retraceable citations and a rights check to a 150–250-word account with a specific unresolved point.
Review and revise
Use these criteria to check your work and choose what to improve.
- The question and conclusion concern the same bounded event.
- Record locators, dates, and attendance numbers match the supplied evidence.
- The account distinguishes direct support, shared sources, and uncertainty.
- Citations support specific claims, and image access is kept separate from reuse permission.

The idea in everyday life
All excerpts are fictional. R1 committee minutes dated September 1, 1963: “Approve a first public evening for September 15.” R2 invitation dated September 12: “First public evening, September 15.” R3 attendance ledger dated September 15: “Harbor Hall opening evening. Total: 42.” R4 newspaper published September 17: “Harbor Hall welcomed its first public club gathering on Sunday, September 15.” R6 minutes dated October 3: “The first public evening took place on September 15. The attendance ledger records 42 attendees.” R5 is an undated photo with caption “Hall opening, 1964,” added around 1985 by an unidentified annotator. No original camera date is available.
Conflicting dates may describe different stages; preserve real disagreement after those stages are separated.
Reconcile conflicting dates: guided practice
Conflicting dates may describe different stages; preserve real disagreement after those stages are separated.
Use paper or a free local text editor. This is an original fictional practice case; do not submit its records to a real service. Start this lesson with these facts, even if an earlier variation changed them. All excerpts are fictional. R1 committee minutes dated September 1, 1963: “Approve a first public evening for September 15.” R2 invitation dated September 12: “First public evening, September 15.” R3 attendance ledger dated September 15: “Harbor Hall opening evening. Total: 42.” R4 newspaper published September 17: “Harbor Hall welcomed its first public club gathering on Sunday, September 15.” R6 minutes dated October 3: “The first public evening took place on September 15. The attendance ledger records 42 attendees.” R5 is an undated photo with caption “Hall opening, 1964,” added around 1985 by an unidentified annotator. No original camera date is available.
1. Label the date roles
Assign each dated item to approval, invitation, occurrence, or later report.
You should see: September 1 approval; September 12 invitation; September 15 recorded event; September 17 publication; October 3 later report.
Dates can differ without contradicting one another when they describe different actions.
2. Weigh the event evidence
Choose the best-supported date for the first public club gathering.
You should see: September 15, 1963, supported by the attendance ledger and near-contemporary newspaper report, with later committee confirmation.
Direct event records and near-contemporary reporting answer the question more closely than an unidentified later caption.
3. Preserve the remaining conflict
Record what R5 says and why its meaning remains uncertain.
You should see: R5 says 1964, but its photo date and annotator are unknown; it may show another event or contain a mistaken caption.
A reasoned preference for one conclusion does not justify inventing an explanation for the conflicting item.
4. Write a qualified timeline note
State the event date and one limitation in two sentences.
You should see: The strongest supplied records place the first public club gathering on September 15, 1963. The undated photograph cannot yet be securely tied to that event.
The final account can be clear while keeping a specific uncertainty visible.
What to finish
Reconcile conflicting dates record with the worked decisions and changed-case check.
Watch for this
Forcing every date into the event-date field or silently deleting contradictory evidence.
How can I tell I understand it?
Build a timeline that distinguishes planning, occurrence, publication, and later annotation. Explain the evidence behind the result and correct any mismatch.
