How do holidays affect business day shipping calculations?
Federal holidays pause business day counting entirely. If a package ships on Friday before a Monday holiday, the earliest delivery would be Tuesday — the holiday doesn’t count toward the delivery timeline, effectively extending delivery by one business day.
What happens if I miss the carrier’s cut-off time?
Missing cut-off times delays processing to the next business day. A package dropped off at 7:00 PM with a 6:00 PM cut-off won’t begin transit until the following business day, adding 24 hours to the delivery window.
