This year the Oscars takes place at the Dolby Theatre in Hollywood on Sunday, Feb. 24. The whole event starts at 8 p.m. ET. 

Of course, if you're interested in the dresses, the pre-event interviews and all the other red carpet stuff, you'll want to start watching at around 90 minutes before at around 6:30 p.m. ET.
