About this category
This category covers tasks performed before sending a document or payment: spelling an amount in words, checking the mathematical structure of an IBAN, or converting between Hijri and Gregorian dates. Each tool solves a different problem, so none validates an entire legal or banking document.
Review every result in context. A structurally valid IBAN does not prove account ownership or status, an amount in words needs currency and decimal checks, and a converted date can differ from an official announcement when lunar observation governs the event.

Preparing a bilingual invoice
- Fix the numeric amount, currency, and decimals.
- Convert the amount into the required language.
- Manually reconcile words and digits before issue.
Adding a bank beneficiary
- Copy the IBAN from a trusted source.
- Check structure and checksum.
- Confirm the name through the bank; validation alone is insufficient.
Planning from a Hijri date
- Convert to Gregorian for initial planning.
- Check the toolβs range and method.
- Confirm with the announcing authority if the date is binding.
Important terms
- Decimal part
- The minor currency unit, whose name and precision vary by currency.
- Checksum
- A mathematical IBAN check that helps detect common entry errors.
- BBAN
- The domestic account portion within an IBAN structure.
- Calendar conversion
- A calculated mapping between date systems, not always an official month-start declaration.
Recommended order
- 1Identify the task and document or transaction.
- 2Enter the value from a trusted source in the relevant tool.

- Number wording needs human review in binding documents.
- Do not rely solely on calculated conversion for legal, religious, or government deadlines.
