Why most rounds are at 14:35 UTC ?
By salyg1n, history, 15 months ago, In English

Just wondered why most cf rounds are at 14:35 UTC? The time period when people can write contests is from the moment they finish their study/work to the moment they go to sleep and it's tight. Does it mean that for people from most timezones it is impossible to participate in codeforces contests? Comment what time do you usually write rounds!

Because you need to put night somewhere, and geographically the most reasonable place for it is in the Pacific Ocean.

    Is it actually there? In china (UTC +8) rounds start at 22:35 and end at least at 00:35. Isn't it inconvenient for them? There are a lot of Chinese on codeforces, but it might have been more if the competition started earlier

      What about people living on the west cost of the US? The time there is UTC-7 in the summer and UTC-8 in the winter. Contests start at 7:35 AM in the summer and 6:35 AM in the winter. If the contests started earlier, wouldn't it be a little early? You can't please everyone at once, the current start time is very good, if not the best.

        Ok I see now. But why we don't have different start times? For example 2 or 3 with equal intervals

      Yes, it's there. If you put night in the Pacific, then contests are late in China, and early for the West Coast of the US.

      Japan and Korea are all in UTC+9. They also have a fair amount of contestants.
      Agree that it might have more contestants if contests start earlier, but I don't think 00:35 is too late for many of them.

      I think there is not a time more convenient than that. You do not have to worry about the contest interfering with any day plans and can take right before bed. I wish that was the time contests were in my time zone.

      But as others said, you can't please everyone, as many have different preferences and different locations. The current time works to allow almost everyone to participate without needing to compete in complete middle of night.

      Having different start times in different contests would also make it easier to miss the contest time due to not remembering properly.

In my opinion, they should have 3 multiple times which should be rotated for contests, each 8 hours apart from each other. So: 6:35 UTC rounds, 14:35 UTC rounds, and 22:35 UTC rounds.

    But we can't expect that many setters that can have time at 6:35 UTC:( They should be there to answer questions, but at that time they may be at work/school or just asleep.

      Sure, that was just an example. But my point is that there should be 3 different times that are rotated for contest times.
