10 views

Reading expiration date codes often involves identifying and decoding various formats. Look for 'best by' or 'use by' labels, which are the most straightforward. For manufacturer codes, understand the format: MMDDYY or YYMMDD (Month-Day-Year or Year-Month-Day). Some brands use Julian dates, where the year is followed by the day count (e.g., 22130 would be the 130th day of 2022). Always verify with the manufacturer's guide if unsure.

FAQs & Answers

  1. What do 'best by' and 'use by' mean? 'Best by' indicates optimal flavor and quality, while 'use by' refers to safety for consumption.
  2. How can I decode a Julian date? A Julian date combines the year with the day of the year. For example, 22130 means the 130th day of 2022.
  3. Where can I find the expiration date code on a product? Typically, the expiration date can be found on the packaging near the barcode or at the bottom or side of the container.
  4. Can I still use a product after the expiration date? It depends on the product. While some may still be safe after the date, others can pose health risks. Always check for signs of spoilage.
