How to find Mars tonight
Look toward the East during the viewing window above. Mars will appear as a steady point of light — planets don't twinkle the way stars do, since they're close enough to show a tiny disk rather than a true point source. Give your eyes 10-15 minutes to adjust to the dark for the best view.
How this is calculated
This answer is calculated live using real orbital mechanics — NASA JPL's published Keplerian orbital elements for Mars, combined with Boulder, CO's real coordinates (40.02°, -105.27°) — not a canned or templated answer. Moon interference is estimated from real moon illumination data.
