A product's warranty period can be established based on several factors, including: The industry standard for the product. What the competition is offering. The period of time during which some percentage of the products will still be functioning correctly.

For example, many warranties for common household items only cover the product for up to one year from the date of purchase. Generally, they are covered only if the product has problems due to defective parts or workmanship. As a result of these limited manufacturer warranties, many vendors offer extended warranties.

Warranty Start Date means the date of manufacture of the applicable Product, as designated by Warrantor. This Limited Warranty is not transferable for any reason, including in the event the applicable Product is sold, traded, transferred or otherwise disposed of in any manner by the original purchaser to another party.

The standard one-year Apple warranty starts when you purchase a product from them. This is also the invoice date. You can buy the AppleCare+ warranty within 60 days after the purchase date to extend the guarantee to two or three years, depending on the product.

A new car's warranty starts on the date it is purchased. To determine how much longer the vehicle will be covered, you can check a car warranty by VIN through a dealership's service department or a vehicle history report.

When developing your product warranty, set forth the length of time that your company is going to stand behind the product. This should typically be at least one year. Many manufacturing warranties establish that there is coverage only if the customer maintains or uses the product as directed.
