You might be thinking: “What if I use FedEx or UPS instead?” Good question. They have similar deadlines, usually one day later than USPS. But they also charge more and might have different drop-off locations. Pro tip: check their websites for “holiday shipping calendar.” It’s a thing, and it’s your roadmap.
Another thought: “What if it’s a homemade cookie box?” Please don’t mail baked goods after December 20th. They’ll arrive stale, or worse—moldy. I learned this when my aunt’s gingerbread arrived looking like a science experiment. Ship non-perishables only after that date, and even then, vacuum-seal everything.
So here’s the honest answer, wrapped in a bow: The last official day is usually December 23rd for express, but aim for December 18th for peace of mind. The real last day, though, is the day you actually get your act together. For me, that’s usually December 26th, when I mail everything for next year. Maybe next year will be different. It won’t, but we can dream.
Now go mail things. Go. I mean it.
