Expert writing Tips

Best practice

When specifying an expiration date with "valid until", always ensure the date format is clear to avoid misinterpretation, especially in international contexts. For instance, prefer using month names (e.g., valid until July 31, 2024) or a universally recognized date format (YYYY-MM-DD).

Common error

Avoid ambiguity by clearly defining whether the "valid until" date is inclusive or exclusive. For example, state "valid until and including July 31" or "valid until, but not including, July 31" to prevent confusion.
