Start with the date in the business record
Keep the invoice, payment, tax record, close file, or policy note that explains why a date matters. That date is the requested date in your business file, even if the official source did not publish a rate on that exact day.
Check whether the chosen source published that day
Some sources publish working-day observations, period rates, or another schedule. If there is no observation on the requested date, record the publication pattern instead of hiding the gap.
FXProof should not silently turn a weekend date into a different date. The proof belongs to the supported source and observation you selected.
Use the available date your rule allows
Your policy, adviser, contract, tax rule, or reviewer decides whether the previous business day, next business day, period rate, or another date is appropriate. Keep that reasoning in the workpaper or business file.
Keep the proof with the explanation
Attach the Signed FXProof Proof PDF to the record that used the selected observation. The proof keeps the source attribution, selected date, rate context, digital signature, document id, payload hash, and verification details together.
Know the boundary before you share it
FXProof documents the selected official reference input. It does not provide legal, tax, accounting, or investment advice, and it does not guarantee recipient acceptance for a missing-date decision.
Show the requested date and selected observation explicitly
Teaching scenario: a record requests Sunday 2026-06-28. Assume the preparer’s publication check found no observation for that date and the applicable policy selected the following available date. Those are stated example conditions, not conclusions proved by the PDF.
| Requested date | Publication available? | Selected observation | Basis and evidence |
|---|---|---|---|
| 2026-06-28 | No, under the teaching assumption; retain the separate publication check. | 2026-06-29 | The preparer’s stated policy selects the following available observation. Download the sample PDF records the selected observation, not the absence of a Sunday publication. |
Official source. Another applicable rule may select a different date. FXProof does not silently move the requested date or establish the legal correctness of that choice.

Inspect a static proof sample before opening a proof for your own selected source and date.

Open year-end use caseQuestions
Does FXProof choose the previous or next business day?
No. Your rule, adviser, contract, or reviewer decides which available date applies. FXProof documents the supported source and date you selected.
Can a proof show that no rate was published on the requested date?
The proof records the selected official observation and its source context. Keep the missing-date explanation in the workpaper or business file.
What should I keep with a weekend-date record?
Keep the business record, the reason for the selected available date, and the Signed FXProof Proof PDF used to support the calculation.
