Yeast starter

[Joon75]

I'm going to make a yeast starter using Brewers friend. It's asking for a manufacturing date for the yeast. I can't seem to find it on white labs vial. Do I use the best before date of 12/25/14? That doesn't seem like it's correct. Thanks!

The date on the vial is when it expires. I believe the label says the manufacture date is 3 months prior (or maybe 4, since I don't have one in front of me). It's tiny, but it's there.

White Labs production date is 4 months previous to the expiration date.
