How much tactic training should you do per day?

If I solve 4 tactics puzzles on chess.com, that would probably take me an hour. I would want to do no more chess after that. "Warm-up."

@62
The time per tactics puzzle should be less than the time per move in a game.

15 minutes thinking time is totally reasonable in a sharp complicated position, where the best move wins and the second best move loses.

++ Agreed, but the same applies even more to a game, where you do not even know if there is a successful tactic or for which side.
If you need 15 min for a puzzle, then you can play nothing shorter than classical, like 90|30.

I don't play online, mostly because my connection sucks.

But the point is that your advice is terrible. In order to get something out of tactics puzzles, you need to think and calculate. If you run through them and just guess a move, that is good for nothing.

Guys I’m actually pretty sure that Magnus trains for 35 hours a day. 

Guess there are only 24 hours in a day I guess he dosent sleep or eat or even that won't make it up or might be he's from a different planet like you

In his book Mind Master: Winning Lessons from a Champion’s Life (at page 79), Viswanathan Anand states the following:
“I remember a conversation with Ken Thompson, one of the inventors of the UNIX operating system and B programming language, both path-breaking foundations of present-day computing. This was in 1998, around the time computers were surpassing us at making tactical moves, but it was universally agree then that humans were much better at strategy. On being asked if computers would ever catch up with humans in strategy, Thompson’s response was, “Of course! Strategy is just long-term tactics.” It was an intriguing observation and over time I have come to realize its proximity to the truth.”
Anand continued: “Chess is 99 percent tactics. If you don’t pay attention to the tactics, no strategy you devise will fetch you rewards. Strategy can’t compensate for mistakes in execution. If you persist with neat execution, it will keep you in the game even if you’re not able to follow a broader strategy. Strategy without tactics, though, falls at the first hurdle.”
Anand’s statements indicate that the vast majority of your time studying chess should be devoted to improving your knowledge and understanding of tactical concepts. You can’t ignore learning strategic positional concepts, but as he indicates, strategy won’t save you if you fail tactically.
I’m currently doing the Woodpecker Method on Chessable (I highly recommend it) and recently did the famous position from Game 11 of the 1995 World Championship match between Kasparov and Anand. Anand had won game 9 to take the lead in the match, but Kasparov struck back in game 10 to even the match. Kasparov’s 29…Rc4 laid a trap by inviting Anand to fork Kasparov’s rooks. Kasparov had tactically seen deeper into the position and after 30.Nb6 Rxb4+ 31.Ka3 Rxc2+ Anand resigned because 32.Rxc2 would lead to 32…Rb3+ (discovered check) 33.Ka2 (forced) Re3+ 34.K moves Rxe1 and Black is up two pawns. Anand never recovered in the match after this game, losing 2 of the remaining 7 games and drawing the others. In Mind Master (page 107) Anand described the game as follows: “Kasparov extended a draw offer on move 19, which I turned down and foolishly threw open my position while attempting to win a rook for my knight.”

Nice riposte. Now all you need is to spend it back 8 years with a time machine.

Magnus carlsen trains for around 30 hours a day, so you should at least train for 25 hours a day to be even decent.

Please go to school and learn about basic time, there's 24 hours in a day and you have to sleep and work

Magnus carlsen trains for around 30 hours a day, so you should at least train for 25 hours a day to be even decent.

Ha ha i train for 1000 hours a minute 😎

I train for a year in a day

Everyone just forget that there are only 24 hours in a day?!?!?!?

25

Studying and training should be based on quality over quantity.

Doing 100 tactics a day and not understanding the "why" behind them is useless compared to doing 3 tactics and thoroughly understanding the "why and how" of each tactic.

One hour per day should be sufficient, although few of us have the time to spare.

Atleast 30mins. Doing 3 or 4 complex problems for high level players and moderately tough problems for intermediate players.

That's not necessarily the best #79, some people are just too lazy and get exhausted even after 2puzzles
