Best practice
Use "was valid from" to clearly specify the start date or time from which a rule, offer, or condition becomes effective. This helps avoid ambiguity about when something applies.
Common error
Avoid stating only the start date without a clear end date for validity. If the validity is for a limited time, always specify both the "was valid from" date and the expiration date.
