Valid until什麼意思
"Valid until" is a phrase commonly used to indicate the period of time during which something is considered valid or effective. It is often used in the context of expiration dates, such as on tickets, passes, certificates, and licenses.
For example, if you have a ticket to a concert and the ticket says "Valid until January 15, 2023," it means that you can use the ticket to enter the concert up until and including January 15th, 2023. After that date, the ticket is no longer valid, and you would not be able to use it to gain entry to the event.
The phrase "valid until" can also be used more generally to indicate the end of a period of validity for any kind of document or agreement. For instance, a contract might have a clause that says "This contract is valid until both parties agree to terminate it," meaning that the contract will remain in effect unless both parties agree to end it.
