They are available year round in the states, even when the season ends there is a good supply of stored dried dates. We keep them in the frig, they go bad after a few weeks room temperature.
No problem! :) You can store them in the freezer for 5 months. I think you should be fine for a month at room temp.
Hi Analucia, I'm in Maryland and when I've gotten 15 lbs of dates, if I didn't eat them up right away, they would last maybe 2 weeks on top of my fridge, in the box. Now when I get them I leave part of them out and put the rest in zip-loc bags in the fridge and they are much less likely to get mold, etc. and could keep a month easy, but usually I eat them up faster than that :)
I think if you are going to keep them 7 weeks or thereabouts, you should probably refrigerate part of them as soon as they arrive.
You know this time of year, you could probably keep them in zip-loc bags, or tupperware in a shady spot outside, it's like a fridge out there most of the time anyway. Only thing to watch for would be ants or other critters getting into them.
