AoE to PST
Anywhere on Earth (AoE, UTC−12) is 4 hours behind US Pacific Time (PST/PDT) in standard time, and 5 hours behind while California, Seattle and Vancouver observe daylight saving time.
When is a “23:59 AoE” deadline in US Pacific?
23:59 AoE = 03:59 next day (UTC−8)
23:59 AoE = 04:59 next day (UTC−7)
So a paper due “15 May, 23:59 AoE” can still be submitted until 03:59 next day in US Pacific, adjusted for daylight saving as above.

Questions
Is AoE ahead of or behind US Pacific?
Behind. AoE is the last timezone on Earth, so it’s always earlier there than in California, Seattle and Vancouver. 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. US Pacific Time (PST/PDT) does change, so the gap is 4 hours in standard time and 5 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.
