Expiration dates on products are often indicated by codes such as 'Exp,' 'Best Before,' or 'Use By,' followed by a date format like MM/DD/YYYY or YYYY-MM-DD. Some products use Julian dates or batch codes that need decoding. If unsure, check the packaging for more detailed instructions.

FAQs & Answers

  1. What do different expiration date codes mean? Expiration date codes like 'Best Before' or 'Use By' indicate the freshness and safety of food items.
  2. How can I decode a Julian date? Julian dates can be decoded by converting the number to its corresponding calendar date, usually represented within a certain year.
  3. Where can I find expiration dates on products? Expiration dates are typically printed on the packaging, often on the bottom or back of the container or box.
  4. Are 'Best Before' dates the same as expiration dates? 'Best Before' dates indicate quality rather than safety, meaning the product may still be edible after that date, while expiration dates indicate the last safe date for consumption.
