I don't know if Wyeast changed their packaging but I'm seeing Google results stating the date of manufacture is on the front of the pack... I only see the use by date. What am I missing?
EDIT
After mass confusion I decided to call Wyeast and the lady said that very recently they changed their packaging from manufacture date to use by date to be more in line with food-type products. So this packet I picked up today is fresh off the lot, it seems. Here's the email response I got from them:

Wyeast recently switched over to a Best if Used By date, which still guarantees our products for at least 6 months from when they are manufactured. When stored and handled correctly (never allowing the yeast to come above refrigeration temperature until ready to activate), the viability and health of the yeast is very stable. We still recommend making a starter when the yeast is within 2 months of the BB date to ensure you are pitching a robust culture.
We are familiar with the homebrew calculators that factor in the manufacturing dates, but these do not correctly reflect the quality of our yeast. Because many if not all are based on other suppliers’ information, and were not consulted or developed with Wyeast, I would like to offer the assurance that our yeast products will perform reliably following our product instructions and guarantee. When viability is incorrectly factored in and a larger than needed started is made, you can end up with too much yeast growth, too rapid of a fermentation, and negative influences on your beer.
