The point of a timeline is to make sources and uncertainty visible—not to force every date into a single answer too early.
Employment dates often arrive in different formats. An applicant may remember “March 2023,” a CV may list “April 2023,” and an employer letter may give a specific day. A reviewer needs to see both the values and the records behind them.
Capture the source before normalizing the value
For each date, save the original wording, source type, file version, page or transcript time, and how precise the date is. Keep “March 2023” as month precision; do not turn it into March 1. Store a full date only when a source actually gives one.
Compare like with like
Normalize formats for comparison, but preserve the original text. “Mar 2023” and “March 27, 2023” may be compatible because one is less precise. “April 2023” and “March 27, 2023” deserve a review question. The system should explain the difference and let a person decide whether it reflects rounding, a start-date convention, or an error.
Resolve with a question and a record
Ask the applicant or case owner to clarify the date convention. Record the answer, who confirmed it, when, and which source supports the decision. Keep the earlier statements visible in history. If the evidence remains unclear, label the field unresolved instead of choosing a convenient value.
Why this helps the handoff
A source-linked timeline lets a reviewer scan career progression without reopening every attachment. It also makes it easier to spot gaps in coverage, confirm which documents still need to arrive, and direct a specific follow-up to the right person.
For immigration matters, the legal significance of a work period depends on the particular case and applicable rules. Ask the responsible immigration professional to interpret it.
