What are the guidelines for refrigerated/frozen breastmilk? Until when are they considered "fresh"?

Refrigerated milk can be stored for 3-8 days. Frozen milk can be kept for 3-4 months (some guides even state up to 6 months) Image taken from: http://www.ameda.com/breast-pumping/storage-handling/storage-guidelines You can also refer to this link for some useful guide on storing breast milk (such as learning how to identify spoilt milk): http://ph.theasianparent.com/rules-of-breastmilk-storage/
