If you watch the UPS delivery trucks as they come through your area then that would be the general time they deliver in your area.
However the delivery times can change from day to day depending on how many packages the UPS driver has to deliver.
The UPS driver around here delivers packages to my door and area around 2:00 PM to 4:00 PM but can deliver as late as 12:00 AM during some busy times.
There's really no way of determining the exact time that UPS will deliver to your address but UPS delivers packages from 9:00 AM to 7:00 PM but can be later during the night.
