Questions
Is AoE ahead of or behind China (CST)?
Behind. AoE is the last timezone on Earth, so it’s always earlier there than in mainland China, Hong Kong and Taiwan. 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. China Standard Time doesn’t use daylight saving either, so the gap is always 20 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.
