How do I read expiration codes?

Expiration codes typically indicate the date by which a product should be used for optimal quality. They can appear in various formats, such as "MM/DD/YYYY," "YYYY-MM-DD," or even as a "best by" date. Some products may use a Julian date, which represents the day of the year, where "001" is January 1 and "365" is December 31. If you're unsure, check the manufacturer's website or contact them for specific guidance on interpreting their codes.
