You've been there. It’s a random Sunday night in July, you’ve got your snacks ready, the couch is calling your name, and suddenly you realize you have no idea if the show starts at 8:00 or 9:00. Or maybe it’s a Thursday and you're terrified of seeing a spoiler on Twitter (I refuse to call it X) before you’ve seen the live eviction.
Honestly, keeping track of the CBS summer schedule is like trying to win a Veto competition while blindfolded.
If you are asking what time is Big Brother on, the answer is usually "it depends." For 2026, we are looking at Season 28. While CBS is notoriously tight-lipped until the actual upfronts, we can look at the established patterns from the last few years—especially the massive Season 27 shift—to pin down exactly when you need to be in front of your TV.
The Standard Weekly Rhythm for Season 28
Basically, Big Brother is a three-headed beast. You have three episodes a week, and they each serve a very different purpose in the game's ecosystem.

For the upcoming 2026 summer season, expect the schedule to look something like this:
- Sundays at 9:00 PM ET/PT: This is usually the "Nomination" episode. We see the fallout from the HoH competition and who gets put on the block.
- Wednesdays at 8:00 PM ET/PT: These have recently become "super-sized" 90-minute episodes. This is where the Power of Veto action happens.
- Thursdays at 8:00 PM ET/PT: The big one. Live evictions. Julie Chen Moonves in a stunning dress telling someone they have to leave the house immediately.
Now, keep in mind that "delayed PT" is a real thing. If you’re on the West Coast, you aren't watching it live with the East Coast folks unless you’re hacking the system with a VPN and a Paramount+ with SHOWTIME subscription. Most of the time, the West Coast broadcast is tape-delayed to hit 8:00 PM or 9:00 PM local time.
Why the Time Always Seems to Change
Ever noticed how one week it’s at 8:00 and the next it’s at 10:00? It’s frustrating.

Sports are usually the biggest culprit. In the late summer, NFL preseason games or major golf tournaments can push the Sunday episodes back by 30 or even 60 minutes. If you see a football game running long on CBS, just know that your recording is probably going to be cut off unless you padded the end of the timer by an hour.
There's also the "60 Minutes" factor. If that show runs long, the whole Sunday night lineup slides.
The Wednesday 90-Minute Trend
Starting in 2025, CBS leaned heavily into 90-minute Wednesday episodes. It seems they realized that fans actually want to see more of the strategy and less of the "scripted" DR sessions. For Season 28 in 2026, insiders expect this trend to continue. It fills the gap left by other summer programming and gives the editors room to breathe.

How to Watch if You Miss the Broadcast
If you miss the window for what time is Big Brother on, you aren't totally out of luck.
- Paramount+: If you have the "Essential" plan, you can stream the episode the very next day (usually by 3:00 AM ET).
- Live Stream: If you have the Paramount+ with SHOWTIME tier, you can actually watch your local CBS station live through the app. This is a lifesaver if you're traveling or don't have a digital antenna.
- The Live Feeds: This is for the true addicts. The feeds are 24/7 (mostly) and show you what’s actually happening versus the "edit" we see on TV.
Key Dates for the 2026 Calendar
We don't have the exact premiere date yet, but casting for Season 28 is already in full swing. Historically, the show kicks off in early to mid-July.
If we follow the Season 27 blueprint, look for a premiere date around Thursday, July 9, 2026. This would allow for a move-in special, followed by the first Sunday episode on July 12. The finale usually lands in late September, just as the fall "prestige" TV starts to roll out.
Actionable Tips for Big Brother Fans
Don't let the schedule ruin your summer. Here is how you stay ahead:
- Check the CBS App every Wednesday morning. They are surprisingly good about updating the "Tonight" banner with the specific air time.
- Follow the "Big Brother" Twitter/X accounts. Not the official one—follow the fansites like Big Brother Network or Hamsterwatch. They will shout from the rooftops if a football game is causing a delay.
- Set your DVR manually. Don't trust the "Series Link" to catch a 15-minute delay. If it's a Sunday in August, manually set your recording to end 60 minutes late.
Knowing what time is Big Brother on is half the battle. The other half is surviving the spoilers until you can actually sit down and watch it. If you're planning on applying for Season 28, remember that the deadline for casting is usually mid-May, so get those tapes in soon.
