Expert writing Tips
Best practice
When specifying an expiration date, always include the year to avoid ambiguity, especially when the document or offer might be viewed across multiple years. For example, use "Valid until December 31, 2026" instead of just "Valid until December 31."
Common error
Avoid specifying only the month and day without the year, as this can cause confusion if the document or offer is viewed in a subsequent year. Always include the full date to ensure clarity and prevent misinterpretation.
