Atlantic Daylight Time (ADT)

Introduction

Atlantic Daylight Time (ADT) is the daylight saving time zone used in parts of Canada and the Caribbean 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 Atlantic Daylight Time is closely tied to the efforts of regions in the Atlantic Time Zone to manage energy consumption and make better use of natural daylight. Daylight saving time was first introduced in Canada during World War I to conserve energy. Since then, the practice has been implemented intermittently and is now a regular part of the timekeeping system in many regions.
