Questions
Is AoE ahead of or behind Japan (JST)?
Behind. AoE is the last timezone on Earth, so it’s always earlier there than in Japan. When a date ends in AoE, it has already ended everywhere else.
Does AoE change with daylight saving time?
No. AoE is fixed at UTC−12 all year. Japan Standard Time doesn’t use daylight saving either, so the gap is always 21 hours.
Why do conferences use AoE?
It’s the latest timezone, so no author anywhere loses part of the final day. If it’s still the deadline date somewhere on Earth, you’re on time. More about AoE.
