Date Calculators

Click Here to Go to the Add/Subtract Date Calculator Tool.

This tool helps to calculate shelf life times, which is the amount of time between a manufacturing date and a best by date.

Note: When you first get to the page it shows “An Error has Occurred”. This goes away once a date and amount of time have been entered in. Simply fill in the fields, choose Add or Subtract, then click “Calculate New Date”, and it gives you the date.

Click Here to Go to the Julian Date Calculator Tool.

This tool helps to convert a 3-digit Julian manufacturing date to a regular Gregorian Date (or vice versa) to determine when a product was made. Although companies usually put either a 1 or 2 digit year (YY) or (Y) before or after the 3 digit Julian date, this converter uses YYYY before the Julian date, so be sure to enter a 4 digit year first. It should be entered in the box like this: YYYY-DDD separated by dashes. Click “Convert” and it will display the Gregorian Date of when your product was made.

Click Here to Go to the Week Number Calculator.

This shows the number of a given week. This form of date is only used on a handful of companies, such as M&M Mars, and Mickeys Beer. It will usually fall in the middle of a lot code.
Explanations for these are found in parenthesis on the product entry’s date code listing in orange.

Click Here to Go to the Ezekiel Lot Code Calculator Tool.

This tool converts Ezekiel lot codes found on their products to a regular Gregorian Date to determine when the product was made. Scroll down the page to the bottom, enter the first 5 characters of the code on the product or its Quik Lock tag, and hit the “Calculate” button.
