For me it’s now Wednesday. I’m having to use the “look ahead” schedules in order to record my favorites. Second hardest to schedule is Sunday.
Sunday. There’s Downton Abbey and Walking Dead and Talking Dead and Last Week Tonight. It’s going to be a pain in the neck when Game of Thrones returns…also on Sundays!
Lookin’ at my TV Calendar, it varies. Two weeks ago I had 12 items on Wednesday. Last week I had 11 items on Monday. This week I had 10 things on Sunday and 9 on both Weds and Thurs.
Saturdays are always the most empty days for me. The only thing I grab then is new episodes of SNL.
I watch all the shows from the week on Friday and Saturday 
Tuesdays, although not for long since several shows are ending soon or recently ended. At one point I was DVRing 10 shows between 8 and 11pm.
Tuesday, I guess. My wife and I both enjoy The Flash and Agent Carter/Agents of SHIELD. But then at ten, she likes Forever and I prefer Person of Interest, so one of us has to wait and watch our favorite later On Demand.
Monday is a close second. We both like Gotham, Scorpion, and Castle, so there’s no conflict… at least, not until Dancing With the Stars comes back. She won’t miss that.
Thursdays. Last night there was a football match on so we couldn’t record both the shows we usually like on a Thursday (usually we watch one and record the other) so have had to download it - legally, FWIW.
For the moment, for my wife and I, Tuesday. We both dig Parks and Rec, and she enjoys New Girl and The Mindy Project. She has some problems on Sunday with Downton and…I think The Good Wife.
We just got rid of cable, which reduces the TV load problem quite a bit, but also got rid of our DVR, which removes the solution.
Monday through Friday (The Price is Right and Jeopardy). I rarely get to watch them, but I usually see them when I’m home sick. The only other show I watch is The Simpsons on Sundays, but I’ve missed the last couple months of that.
Sunday, no contest. I watch EastEnders in the afternoon. Once Upon A Time. Downton Abbey. Call The Midwife. Mad Men. Walking Dead. Talking Dead. All these shows are on Sundays, not all of them at once, thank god. Mythbusters? not sure what day, but I don’t like it so much any more. The Simpsons, though I haven’t watched in a long time, so that one is off the table.
During the week I will watch Fashion Police and Grey’s Anatomy. That’s it. I wish some Sunday shows could be spread out during the week (though some on PBS are re-run though I find it hard to determine the times, the program guides are generally wrong. Walking Dead seem to be on all night on Sundays.)
Sunday!
Simpsons (yes), Brooklyn 9-9, Family Guy, Bob’s Burgers (best show on TV)
Shameless (best show on TV), Walking Dead
I guess for me it would be the Wednesday lineup on ABC (The Middle, The Goldbergs,
Modern Family and Blackish), followed by Mondays with Gotham and Fashion Police.
Tuesday. Chopped and Face Off are the only shows I make any effort to watch as they air.
All days are interchangeable. Tivo is my friend.
Tuesday was a little tough this week. I don’t have TiVo, DVR or on demand or even a stone age VCR. I skipped NCIS and NCIS New Orleans to watch the replay of last season’s last episode of “Rizzoli and Isles” because it was a lead in to this season opener. Next week will be ok since both “Rizzoli and Isles” and “Justified” are on several times.
Most nights are just a wasteland with an occasional island of mediocre dreck. Oh except Wednesday. That night I read.
Sunday. Shameless, Episodes, Walking Dead, The Good Wife, Family Guy. I actually watch most of it later on On Demand so I end up stretching my Sunday watching out over the following week.
Wednesday for me, thanks to the double-header of NXT and Lucha Underground.
Tuesday definitely.
I have no idea. I can’t remember the last time I watched a show as it was broadcast. My life just doesn’t work that way any more .
I honestly have no idea which day most of the shows I watch are aired. Almost the only thing we make a point to watch ‘live’ are sporting events; everything else gets recorded and watched on the DVR. Occasionally we end up actually watching a show as it airs ‘by accident’, and it always unnerves me when I can’t skip through the commercials…
I use a DVR too, but mine only has two tuners (meaning only two programs can be recorded at the same time). On a Sunday night at 9pm, there might be programs on four or five channels I want to watch (CBS: The Good Wife; PBS: Masterpiece; HBO: Game of Thrones or whatever; Showtime; Shameless or whatever; and maybe another one). PBS, HBO and Showtime repeat their 9pm programs later that night, so I record them later.
Owning a DVR doesn’t eliminate all issues.
