Budapest is 9 hours ahead of Portland
Best overlap: 8:00 AM to 9:00 AM in Portland is 5:00 PM to 6:00 PM in Budapest.
8:00 AM to 9:00 AM in Portland is when Budapest is also working, at 5:00 PM to 6:00 PM their time. Because Budapest is 9 hours ahead of Portland, the shared window is only about 1 hour. A fixed slot at 8:00 AM in Portland (5:00 PM in Budapest) saves a lot of back-and-forth.
