Valid for的意思

"Valid for" is a phrase that indicates something is valid within a specified period or for a particular purpose. It is often used to indicate the period of time during which something is considered valid or effective, such as a coupon, a ticket, a warranty, or a license.

For example:

• A coupon might say "valid for 30 days from the date of issue."
• A ticket for an event might say "valid for admission on the day of the event only."
• A warranty card for an appliance might say "valid for two years from the date of purchase."
• A passport might say "valid for travel until the expiration date."

In each of these cases, "valid for" is used to specify the duration or the conditions under which the document or item is considered valid.
