Pacific Islands Time Zones

Fiji, Samoa, Tonga, Guam — date line complexity and DST rule changes.

Pacific nations sit near the International Date Line Explained and have changed offsets for trade and politics. Samoa skipped a calendar day in 2011; Fiji and Tonga have toggled DST. Flights, cruises, and telecom ops need current IANA data — not old maps.

Sample IANA zones

  • Pacific/Fiji — Fiji (UTC+12, check DST in IANA)
  • Pacific/Apia — Samoa (UTC+13, date-line history)
  • Pacific/Tongatapu — Tonga (UTC+13)
  • Pacific/Guam — Guam (UTC+10, no DST)
  • Pacific/Honolulu — Hawaii (UTC-10; United States Time Zones Guide)

Tips

  • Date-line flights: verify **calendar date** and local clock
  • Vs New Zealand and eastern Australia: DST combinations vary
  • Never use vague "Pacific time" on global invites
  • Use Convert and Countries for live offsets
