Holiday shopping is stressful enough but, in some ways, the digital age makes things even worse. Sure, it allows shoppers to avoid parking lot disasters and long lines but it creates a whole new kind of mayhem. This year alone, the Internet contributes to over $2.2 trillion dollars in annual retail sales, making the post office the epicenter of chaos. Unpredictable weather is one of the biggest factors in delayed deliveries.

Don’t let the whole gift-giving frenzy disrupt your holiday excitement. There’s still plenty of time to relish in ugly Christmas sweater parties, tree hunting and hot chocolate in front of the fireplace, without worrying about your gift arriving on time. To stay on the nice list, send those packages early and mind these key holiday post office dates to ensure they are received in time for Christmas.
