Well, I've been waiting on some equipment for a while so my yeasties have been in the fridge waiting patiently and I wondered to myself what the loss in viability is with age. I think the born on date has them at June 7 or so, any ideas when losses start to occur?

It's Wyeast American Wheat I think, but I'll check. I think the curiosity is more academic than functional, but still fun to know

Check the best by date and the manufacture date and no matter what it says make a starter.

After it leaves Wyeast the viability starts to go down, use this: http://www.mrmalty.com/calc/calc.html it lets you put in the manufacture date to adjust the size of your starter.

BTW, I am 99% sure it will be fine.
