Tonga Summer Time (TST)

Introduction

Tonga Summer Time (TST) is the time zone used in Tonga during the daylight saving period. It is 14 hours ahead of Coordinated Universal Time (UTC+14:00). This time zone is unique due to its significant time difference from UTC, making it one of the first time zones to welcome a new day.

Time Zone History

Tonga Summer Time was established to make better use of daylight during the longer days of summer. The decision to adopt daylight saving time was influenced by the desire to provide more daylight hours for evening activities and to align more closely with trading partners. Over the years, there have been several changes to the observance of daylight saving time in Tonga, reflecting shifts in policy and public preference.

Geographical Coverage

Tonga Summer Time is observed throughout the entire Kingdom of Tonga, an archipelago in the South Pacific Ocean. Tonga consists of 169 islands, of which 36 are inhabited. The country's unique geographical position near the International Date Line means it is one of the first places in the world to experience a new day.

Daylight Saving Time (DST)

Daylight saving time in Tonga typically begins in late October and ends in early April. During this period, clocks are set one hour ahead to make better use of daylight during the evening hours.
