The dark sky table shows the Pacific Daylight Saving Time (PDT) times for sunset, astronomical twilight ends, astronomical twilight starts, sunrise, moonrise, moonset and total moon-free, twilight-free viewing time for Portland, Oregon, U.S.A. (Longitude: West 122.68 degrees & Latitude: North 45.52 degrees).
