What is daily chess?

Hi seems like a simple question, but you don't know what you don't know. I can't find the answer:

'Daily chess' means one move a day? Or it means the game lasts for 24 hours? 

It's a name Erik came up with for correspondence chess.  Games usually last weeks.  You can take up to whatever limit you are playing.  Three day seems popular.  Lets you root around the databases and try to figure out the best move.  In the old days of postal correspondence, the player with the better chess library often won.  There are some sites that allow computer program use but this isn't one of them.  Hope that helps.

Ah ok so the game lasts as long as it lasts, as long as you make one move a day? I see now, thanks. 

Correspondence chess had too many syllables.  Daily chess is a ludicrous appellation.

Chess.com "daily" chess offers time controls of anywhere from 1 day to 14 days per move.  So the game could conceivably last for a year (or more) depending on the actual time per move taken by the players, and the total number of moves in the course of the game.

Note also for "daily" chess, one is allowed to consult books and databases, but not chess engines (for calculating moves) or input/help from humans.  This is a standard rule for most correspondence chess.  For "live" or over-the-board (OTB) chess, the use of ANY kind of external resource or aid is prohibited!

A lot if intellectual answers for a simple concept. LOL

Um, how would anyone know if you were consulting a chess engine vs a chess book?

You have to join this club to find the answer to that....

Bruh why, bumping old resolved forums is not polite

Very well explained. 

I would ask you guys if on daily chess we can use additional chess board to move lines. Thank you!

Absolutely; in fact it's kind of encouraged to help you play the best game possible.  Just don't boot up an engine or use an endgame tablebase or ask anyone for advice.

What would a PGN be considered? An engine? Because I don't even think that would be that helpful in a rapid game (maybe 30 min), it would take too long to find the variation you wanted and even then people play very odd moves that are not in your PGN. 

LOL....Okay thanks!

I don't know where you got that from but no... chess.com has 2 sections on their page, "live" and "daily". Daily chess there is no time limit for moves at all. I am playing a game in the "daily" section, and my timer reads "14 days", not 5 minutes.. "Live" on the other hand is where Blitz/Rapid/Bullet resides where moves are more strictly timed. So I don't know where you got that notion, but on chess.com specifically, you are mistaken. Maybe on lichess or at your local club you use "daily" differently, but here we are specifically referring to chess.com 

This guy has 0 sense of humor.....

LOL I do have a legitimate question about daily games. They're great for me (very busy person) to get games in throughout the day. Sometimes looking at a position for an hour multiple times before I choose a move. However I don't understand how databases are allowed. What is really the difference between an engine and a database in this circumstance? A database is likely still going to show the best moves or at least the correct ideas, so what is the point? Sure I could pop my phone out and look at my engine in any time controls but in the daily controls it is totally okay for me to get my moves while in game from the database? That makes me not want to play daily anymore, which is a shame. I get in the old days they had to research their library to find the ideas and moves. That took effort and time. Now I can play 99% accuracy and won't get banned for cheating if all I'm dong is using the explorer? That seems wrong.

@loc77etc.

It's surprising how quickly book moves run out in most games.  My own personal rule was always to follow along right up to where I didn't understand the move and then substitute something I did.  Yes there are certain sequences where you can stay in book for maybe half the game, but that still leaves plenty of time for you to play chess.  It's not for everyone obviously, and there is at least one club (Circle of Trust maybe?) whose members promise not to use any help.  Since your opponent has the same opportunity as you do to do research, it's a level playing field.  Most players look at each game as the opportunity to try and craft a perfect game.  It's too much stress for me frankly; once I found myself dreaming about my chess games I had to stop.  Waking up in the middle of the night to run to a board and try out an idea seemed a recipe for madness.  If you don't take it too seriously though, it can be a lot of fun.  My $.02...

Well I'd say an openings database can't really be compared to an engine because it's just openings. Eventually one of you is going to play a "novelty" and it's just chess from then on out. The openings database will just say "no games found in this position" or something like that.

Engines calculate in real time the best move in any presented position. All the way to the end game it will calculate at least how to draw the game if that's possible. It's just waaaay more powerful than an openings DB.

Openings are a 2 way street of course so just having one isn't really enough to win. Your opponent won't be playing the moves that lead in your favor, and you will have to counter that, eventually by playing a "novelty" thus kicking off the true game. Even if you both  just played into a specific line cooperatively you'd eventually end up in a single historical GM game that could've ended in a resignation or agreed draw at which point you'd be forced to play out to the rest of the game without help.

The idea is that daily games are going to be very very accurate. You could potentially play a GM level game as an 800elo and that's really the expectation. The result of that however is typically very long and dry games, that you know the result of long before anyone is checkmated. So, really just a different flavor of chess, as you said somewhat similar to correspondence.
