AoE to AEST
Anywhere on Earth (AoE, UTC−12) is 22 hours behind Australian Eastern Time (AEST/AEDT) in standard time, and 23 hours behind while Sydney, Melbourne and Canberra observe daylight saving time.
When is a “23:59 AoE” deadline in Sydney?
23:59 AoE = 21:59 next day (UTC+10)
23:59 AoE = 22:59 next day (UTC+11)
So a paper due “15 May, 23:59 AoE” can still be submitted until 21:59 next day in Sydney, adjusted for daylight saving as above.

Questions
Is AoE ahead of or behind Sydney?
Behind. AoE is the last timezone on Earth, so it’s always earlier there than in Sydney, Melbourne and Canberra. 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. Australian Eastern Time (AEST/AEDT) does change, so the gap is 22 hours in standard time and 23 hours during daylight saving.
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.
