Time Differences Between Tahiti and U.S. Time Zones

Tahiti (French Polynesia) operates on Tahiti Time (TAHT) = UTC−10:00 year-round (no daylight saving). The time difference to U.S. zones varies seasonally due to U.S. daylight saving observance.

Key Reference Points

  • Tahiti = Hawaii time year-round (both UTC−10, no DST)
  • Tahiti = Los Angeles (PST) + 2 hours (standard) / + 3 hours (daylight)
  • Tahiti = New York (EST) + 5 hours (standard) / + 6 hours (daylight)
  • Tahiti = UTC−10:00 — same as Honolulu, Adak, Papeete, Cook Islands

Practical Tips

  • Use UTC as anchor: Tahiti = UTC−10 always
  • For scheduling: "Tahiti time + 5/6 hours = US East Coast" depending on season
  • French Polynesia spans multiple zones: Marquesas (UTC−9:30), Gambier (UTC−9:00) — but Tahiti is the population/government center

The original query's data table contained inaccuracies (e.g., Guam, Wake, Johnston, Midway are U.S. territories but not "America" in the continental sense; Hawaii is UTC−10 not UTC−10/+10). This corrected version uses standard IANA time zone designations.
