What is the best way to calculate a date difference?

Is there a way to tell the Brew date of Miller High Life by the Expiration date on their beer?

• I know Busch and Budweiser (same company) includes their "Born on" date, which I can tell a difference between beers that have been brewed a long time ago, as compared to freshly brewed beer... So, I know on Anheuser Busch brewed beers, how old they are... But, I do not know on other brands even though I would not mind buying other brands if I knew when they were brewed. The other brands have "Best if consumed by" and the like, on their bottles... It's basically an expiration date. Can you tell me on Miller beers, or otherwise, how far to back that up to know the brew date or the "Born On" date, per say? Thanks

• Answer:

  The date on Miller products is a Do Not Sell date that indicates the last day retailers should sell the product. This date is 120 days from what would be the "born on date". So whatever that date is on the bottle, count back 4 months and you have a good ballpark of when it was "born".
