I look at this website: https://time.is/UTC-12

and it tells me that there's a 6 hour time difference between UTC-12 and ET.

I know about an AoE timezone that as long as it's xPM in any part of the world you are still within the deadline. Is this the same? I would really appreciate a quick response for this short question.

  • This really depends on whose deadline you are talking about. There is no general answer to this question. Usually deadlines are clear - either the timezone is implied by natural geographic restriction (ie: deadline for a University paper, application, etc) or the timezone for the deadline will be explicit. If it is ambiguous to you, the only thing you can do is ask about the specific deadline you have in mind. Do this ahead of time - excuses don't usually matter for a lot of deadlines. If you miss them based on a half-baked assumption you made, that's usually your problem to deal with. – J... Jan 22 at 18:12

UTC-12 means that it's 12 hours behind UTC. That's the maximum distance in our 24 hour day clock. So UTC-12 is the timezone where calendars end.

That's probably the motivation behind using it as a deadline. For example, if the deadline is January 31st UTC-12, then as soon as it's not January anymore anywhere, the deadline has passed.

What's the difference with AoE ("Anywhere on Earth")?

AoE could be interpreted to apply daylight savings time. UTC never applies daylight savings time.

  • So is this similar to the AoE deadline? – the_dance Jan 21 at 22:48

    @the_dance yes but it's more precise. – ObscureOwl Jan 21 at 23:00

    note that while UTC-12 is the maximum distance in that direction, going the other direction there is an UTC+14 timezone, meaning there's actually a 26 hour difference between the two ends of the timezone map – SztupY Jan 21 at 23:42
  • @SztupY I didn't know that, but reading about it it's pretty interesting. – ObscureOwl Jan 21 at 23:46

    (+1) For those of us more geographically minded, this time zone is in the central Pacific, and is two hours behind Honolulu Standard Time. – cag51 Jan 21 at 23:53
