In humid summer weather, only a few days! That's one of the reasons I buy the ones with the color marker. I can quickly see if they are in need of drying out. If they are in sealed (plastic, not paper) bags, they can last indefinitely, but once exposed to the atmosphere they start to take up water immediately.
When purchased in camera stores or electronics shops, they tend to be in fancy containers and rather expensive for what they actually are. If bought in chemical supply stores (the Yellow Pages are your friend) they are cheap as dirt, but you have to supply your own smaller 'working' containers. As I said, I use empty tea bags for small sachets, but for larger amounts pour 3-4 tablespoons full into coffee filters, fold the edges and tape them down. Works fine.
