“Valid From and Valid To” or “Valid From and Valid Until”?

Learning if “Valid From and Valid To” or “Valid From and Valid Until” is correct, and what it means is very important because it is used in one of the most vital industries on the planet: the pharmaceutical. Read on; you’re in the right place to never doubt again.

“Valid From and Valid To” or “Valid From and Valid Until”?

“Valid From and Valid To” or “Valid From and Valid Until” are correct when used to say that something, usually a product, is good for use between two specific dates. In both, the word “to” and the word “until” do not include the final date.

The use of “Valid From and Valid To” or “Valid From and Valid Until” is completely interchangeable. You can consider these two expressions to be synonyms. The difference should be made with the expression “valid through” which implies the product in question is valid through the indicated date.

For example, if you won a coupon that said: “This coupon is valid through 2022”, the prize would be yours as long as you exchange it before 12/31/2022.

Valid From and Valid To

The expression “Valid From and Valid To” is perfectly correct and used to denominate the time length in which a product, service, or prize is usable. The use of the word “to” in the phrase implies that the ending date is not included; this is paramount to avoid confusion.

1. The offer is valid from March to September of the current year.
2. She said the repair had a warranty; valid from this moment to September the 1^st.
3. The content of this box is valid from March to October 2022.
4. Your license is valid from January 1^st to December 31^st; not a second longer.
5. The coupon is valid from March 1^st until June 1^st, three months exactly.

Valid From and Valid Until

The expression “Valid From and Valid Until” is correct and used to say that a product, service, or prize is usable during a certain period. The use of “until” before the final date doesn’t imply the end date is included in the period indicated.

1. All bids are valid from this moment and until the end of the match.
2. The visitor’s ticket is valid from the moment you walk in until the moment you leave.
3. The present offer is valid from today until the end of the semester only.
