Daylight Savings Time

March 29, 2023

Daylight Saving Time (DST) is a practice of setting the clocks forward one hour from the standard time during the summer and back again in the autumn. Although it was initially intended to make better use of natural daylight and save energy, today, it remains a subject of controversy. This article examines the legacy of DST, focusing on its history, advantages, disadvantages, and controversies.

The Origins of DST

The practice of DST began in Canada in 1908 when the residents of Port Arthur, Ontario—today’s Thunder Bay—turned their clocks forward by one hour to start the world’s first DST period. Other locations in Canada soon followed suit. DST caught on globally after Germany and Austria introduced it on April 30, 1916, to minimize the use of artificial lighting and save fuel during World War I. Today, approximately 70 countries around the world observe DST.

Advantages of DST

One of the primary benefits of DST is that it maximizes the amount of natural light available during the longer days of summer. This practice can reduce energy consumption and greenhouse gas emissions, as people rely less on artificial light and air conditioning. Furthermore, DST can reduce traffic accidents and fatalities, as there is more daylight during peak driving hours.

Disadvantages of DST

Despite the benefits of DST, it is not without its drawbacks. Many people argue that the disruption of the body clock due to the time change has adverse health effects. A study conducted by the American Academy of Sleep Medicine showed that the incidence of heart attacks increased by 24% on the Monday following the spring DST transition. Another study found that DST could cause a higher rate of workplace injuries, due to decreased alertness and concentration. Moreover, many people find the time change disruptive to their daily routines and sleep patterns.

Controversies Surrounding DST

The recent confusion surrounding DST in Lebanon highlights some of the controversies surrounding this practice. In Lebanon, the government delayed the start of DST by a month, causing confusion among institutions and individuals. While no reason was given initially, a leaked video showed Parliament Speaker Nabih Berri urging Prime Minister Najib Mikati to postpone DST to allow Muslims to break their Ramzan fast an hour earlier. As a result, airlines, cellphone operators, schools, and workplaces are no longer following the same time.

Another controversy surrounding DST is that it is no longer relevant in modern times. With most appliances consuming energy running at all hours of the day, DST has lost its energy-saving potential. Furthermore, many countries have either abandoned DST or are considering doing so. For example, the European Union proposed abolishing DST in 2021, but the proposal was postponed until 2022.
