When a "contradictory" date isn't a contradiction

Why Hijri-to-Gregorian date conversion can produce a credibility finding that isn't one — and what to check before you rely on it.

A credibility finding can start with something this small.

A client rarely fixes an event to a Gregorian date at the time it happened. More often it's anchored to a reference point — a religious month, a harvest, a wedding, the week a relative was born. That's a perfectly coherent way to remember something. The problem starts later, when that reference point gets converted into a precise calendar date for a record — once at screening, and again, independently, months later at the substantive interview or in a witness statement. The two conversions can land on different Gregorian dates even though the client's underlying account never moved at all.

On paper, that looks like an inconsistency. It isn't one. It's two people doing the same conversion at two different times.

This is exactly the trap the interpreting rulebook exists to catch: interpret the date as the witness actually gave it — Hijri, seasonal, or approximate — and flag which calendar it came from, rather than silently supplying a Gregorian figure that reads as more precise than what was said.

What to check before treating a date discrepancy as a credibility point

  • Was the original account given as a Hijri date, a seasonal or religious reference, or an approximation — or was it already a fixed Gregorian date?
  • Was the same reference point converted the same way at screening, at the substantive interview, and in the witness statement — or did each document do its own conversion?
  • Can the interpreter confirm, on the record, which calendar the client was actually using?
  • At the hearing, has counsel established the reference point before asking the witness to commit to a specific Gregorian date?

This is a pattern I flag routinely doing NRPSI-registered interpreting work across asylum and immigration settings — and it's the kind of question a written dialect and origin-analysis note exists to answer properly, where the calendar issue itself needs establishing for the tribunal rather than assumed away.

Not sure whether a date discrepancy in your case is genuine?

Talk it through before you instruct, or ask about a written consultancy note. No obligation, and case evidence is not discussed on the call.
