Seeds seeds seeds

Ok so I have some seeds that are pretty bad ass..problem is I got awhile till my nxt grow..so wat I need help on is how long do seeds originally last? On average?

they can germinate after years.
but i would germinate after a year or so.. not any longer..

store them in the fridge if you can and make sure they are in an envelope or something where light is not getting at them and you should be fine.
