CBS has announced its fall schedule, including the beginning of Survivor 33, aka Survivor Millennials vs. Gen X, and the finale of Big Brother 18.

Both shows will share the same three-hour prime-time block, airing 90-minute episodes each on Sept. 21. That’s the same day/time as last fall.

CBS is airing just one unscripted series this fall: Survivor. That’s because The Amazing Race is not on the schedule, as it will not air until midseason, or perhaps to fill a timeslot of a new show. (There are fewer reality series on broadcast prime-time schedules this fall.)

Survivor 33’s premiere, BB18’s finale

Here are the dates:

• Survivor Millennials vs. Gen. X premiere: Wednesday, Sept. 21, 8 to 9:30 p.m.
• Big Brother 18 finale: Wednesday, Sept. 21, 9:30 to 11 p.m.
