In NY, if you buy meat from a retail establishment, they are required to date cyrovaced meat. The retail store, Stop and Shop, your butcher etc, is required to date it based upon when they purchased it.
If you bought your meat from say Restaurant Depot, it is considered a wholesale establishment and they are not required.

Section 240. Length of storage period
1. No person or corporation shall keep or permit to remain in any refrigerated warehouse or locker plant any article of food beyond the time when it is sound and wholesome and fit to remain in storage. If any article of food is found to be fit for immediate consumption, but unfit for further storage, such article of food shall at once be re-moved from storage and not again stored. No article of food shall be kept or permitted to remain in any refrigerated warehouse for a longer aggregate period than twenty-four calendar months, except by order of the Commissioner. Upon evidence satisfactory to him that the food is sound and wholesome and fit for further storage, the Commissioner may, in his discretion, grant an extension of the storage period. He may, in his discretion, cause any articles of food to be examined to ascertain if the food is sound and wholesome and fit for further storage.
