US Television and Broadcast Time Zones: How '8/7 Central' Works

When a network promo says "8/7 Central," the show starts at 8:00 PM Eastern and 7:00 PM Central. Same live feed, two different clock readings. That shorthand is the first clue that US television runs on a carefully stacked set of time zone compromises, and the Mountain and Pacific audiences get something entirely different.

Networks anchor their schedule on Eastern Time. Central receives the identical live signal, just one hour earlier by the clock. Mountain and Pacific stations get separate, delayed feeds so that prime time lands at a watchable hour everywhere. The whole machine exists because a simultaneous national broadcast would put evening programming in the middle of the California workday.

What '8/7 Central' Actually Delivers

The notation means exactly what it says: 8:00 PM Eastern, 7:00 PM Central. One signal leaves the network, and both zones receive it at the same instant. When a character speaks at 8:04 PM in New York, Chicago hears it at 7:04 PM. No delay, no separate edit.

Mountain and Pacific are not part of that feed. They wait.

Network Prime Time Across Four Feeds

Network prime time spans 8:00 PM to 11:00 PM ET and PT. Eastern and Pacific share the same clock hours; Central and Mountain run an hour earlier.

• Eastern Feed: 8:00 PM, 11:00 PM ET
• Central Feed: 7:00 PM, 10:00 PM CT (same live signal as Eastern)
• Mountain Feed: 7:00 PM, 10:00 PM MT (separate feed)
• Pacific Feed: 8:00 PM, 11:00 PM PT (delayed three hours from Eastern)

Mountain Time is the odd fit. It is the only zone that does not mirror either coast's clock pattern. Mountain audiences start prime time at 7:00 PM, matching Central hours, despite sitting just one hour ahead of the Pacific zone.

Why Both Coasts Get the Same Clock Schedule

Americans go to bed at roughly the same local times. A drama that ends at 11:00 PM in New York ends at 11:00 PM in Los Angeles, three absolute hours later. Networks learned this through trial in the 1950s and 1960s. Airing everything simultaneously nationwide would have put prime time at 5:00 PM in California. Working adults were not home.

The cost is delay. Scripted shows reach the West Coast on a three-hour lag. Live events, however, often break the pattern.

Live Events: Super Bowl, Oscars, and the National Window

Live broadcasts chase the largest simultaneous audience. The Super Bowl kicks off near 6:30 PM ET. That slot is deliberate.

• East Coast: pregame at 5:30 PM, kickoff at 6:30 PM
• West Coast: 3:30 PM PT, a Sunday afternoon
• Game ends around 10:00 PM ET, 7:00 PM PT

The Oscars follow the same logic, starting at 7:00 PM ET and 4:00 PM PT. West Coast audiences watch in late afternoon. Networks accept the grumbling because the Eastern audience, the largest segment, gets a full prime-time experience.

Monday Night Football starts at roughly 8:15 PM ET. That 15-minute offset clears pregame coverage and avoids a hard top-of-the-hour clash with other programming.

Morning Shows: Live East, Taped West

"Today" and "Good Morning America" air 7:00 AM to 9:00 AM ET. That is live for Eastern audiences. A straight simulcast would hit the West Coast at 4:00 AM PT. Most affiliates run a tape delay at 7:00 AM PT instead.

The result: a "morning" show that West Coast households see at breakfast is already three hours old. Any breaking news or date reference has aged.

Sports: East Coast Games, West Coast Pain

Leagues schedule around Eastern audiences because that is where the largest population sits.

A 7:30 PM PT tip-off in Los Angeles means 10:30 PM ET in New York. A two-and-a-half-hour game ends at 1:00 AM ET. East Coast fans regularly lose sleep over West Coast basketball and baseball.

The reverse hits harder on weekends. A 1:00 PM ET NFL game kicks off at 10:00 AM PT. California fans who want Sunday morning football get it, whether they want it or not.

The NFL places its biggest matchups in the 4:25 PM ET slot. That is the national window: 1:25 PM PT on the West Coast, late enough to feel like game time, early enough to avoid the midnight problem.

Radio Syndication and the Drive-Time Puzzle

Radio chases commuters. Syndicated talk shows need to hit morning and evening rush hours in every zone.

A program hosted from New York might air live for Eastern stations, replay on delay for Central and Mountain, and replay again for Pacific. Some shows cut a separate "west feed" for the coast. A program that airs at 9:00 AM ET could reach Denver at 7:00 AM local and Los Angeles at 6:00 AM. Each station fits the show to its own traffic pattern.

Streaming Cuts the Cord

Streaming dismantles the broadcast clock. Netflix, Hulu, and Disney+ release on demand. No prime time, no zone notation. A new season drops at a single global moment, and audiences hit play whenever they want.

Live sports and news remain tethered to the old system. Scripted shows do not. The "8/7 Central" tag still appears in streaming listings, but it is becoming a fossil. Younger audiences who never watched linear TV do not think in time zone math at all.

For live streaming of sports, awards shows, and breaking news, the old rules hold. The Super Bowl is still the Super Bowl regardless of platform. But the era of a household scheduling dinner around an 8:00 PM network drama has ended.
