Anywhere on Earth (AoE) is a calendar designation which indicates that a period expires when the date passes everywhere on Earth.
The last place on Earth where any date exists, is in the IDLW (International Date Line West) time zone, on the "Hawaii side" of the International Date Line, where
Howland Island and
Baker Island are situated. The IDLW time zone has the largest negative UTC offset of all time zones (-12 hours). Therefore, it is the last time zone for any day to exist, and the day ends AoE when it ends in the IDLW time zone.
