Amazon Summer Time (AMST)

Introduction

Amazon Summer Time (AMST) is the daylight saving time zone used in parts of Brazil during the summer months. It operates three hours behind Coordinated Universal Time (UTC-03:00). This time zone is essential for making better use of daylight during the longer days of summer, helping to save energy and provide more daylight in the evening.

Time Zone History

The history of Amazon Summer Time is closely tied to Brazil's efforts to manage energy consumption and make better use of natural daylight. Brazil first adopted daylight saving time in 1931, and since then, the practice has been implemented intermittently. Amazon Summer Time was established to provide more daylight during the evening hours in the summer months, aligning with the practice of daylight saving time observed in many parts of the world.

Geographical Coverage

Amazon Summer Time is observed in several states in the Amazon region of Brazil, including:

  • Acre
