do ups deliver on christmas day

I'm sorry, but no, UPS does not deliver on Christmas Day. Most businesses and organizations are closed for the holiday, and even if they were open, there wouldn't be enough people working to operate the delivery service. The only exception might be emergency services like the police or fire department, but even they might have limited availability. It's best to plan ahead and have all your deliveries made before Christmas Eve if you want to make sure your gifts are received on time.
