Daylight Saving Time

What Is Daylight Saving Time?

Daylight Saving Time (DST) is the practice of moving the clocks forward one hour from Standard Time during the summer months and changing them back again in the fall. The general idea is that this allows us all to make better use of natural daylight: moving the clocks forward one hour in the spring grants us more daylight during summer evenings, while moving clocks back one hour in the fall grants us more daylight during winter mornings. However, DST has many detractors—and rightfully so! 


The first true proponent of Daylight Saving Time was an Englishman named William Willet. A London builder, he conceived the idea while riding his horse early one morning in 1907. He noticed that the shutters of houses were tightly closed even though the Sun had risen. In “The Waste of Daylight,” the manifesto of his personal light-saving campaign, Willet wrote, “Everyone appreciates the long, light evenings. Everyone laments their shrinkage as the days grow shorter; and nearly everyone has given utterance to a regret that the nearly clear, bright light of an early morning during Spring and Summer months is so seldom seen or used… . That so many as 210 hours of daylight are, to all intents and purposes, wasted every year is a defect in our civilization. Let England recognize and remedy it.”




World War I Led to Adoption of DST

After World War I broke out, the government and citizenry recognized the need to conserve coal used for heating homes. The Germans were the first to officially adopt the light-extending system in 1915, as a fuel-saving measure during World War I. This led to the introduction in 1916 of British Summer Time: From May 21 to October 1, clocks in Britain were put an hour ahead.

  •  Fall back (turn clocks back and gain an hour)

Origin of the Days of the Week and the Months of the Year



Leap Year


  • A Leap Day, February 29, is added to the calendar during leap years. This extra day makes the year 366 days long – not 365 days, like a common year.
  • Leap days are needed to keep our calendar in alignment with the Earth's revolutions around the Sun. Without an extra – or intercalary – day on February 29 nearly every four years, we would lose almost six hours every year. After only 100 years, our calendar would be off by approximately 24 days in relation to fixed seasonal days days like the vernal equinox or winter solstice.
  •  Roman general Julius Caesar implemented the first leap day in his Julian Calendar, which he introduced in 45 BCE (Before Common Era). A leap day was added every four years. At the time, leap day was February 24, and February was the last month of the year.
  • It  is still associated with age-old customs, folklore and superstition. One of the most well-known traditions is that women propose to their boyfriends, instead of the other way around.

Time Clauses: Grammar and Exercises

Future with time expressions 
(after, as soon as, before, till, when, while ... )

The time clauses in the English language are introduced by conjunctions such as after, as soon as, before, till, until, when, whenever, while or time expressions such as the minute, the moment, etc.

We do not use the future tense (will) in a time clause to describe future activities.



Compare:

  • I'll come back home and I'll do it.  
      I'll do it when I come back home.  (when I come is the time clause)
  • You will push this button and the door will open. 
       As soon as you push this button, the door will open.

  • Don't stand up. First I'll tell you. 

       Don't stand up till (until) I tell you.

  • You'll need my car. Take it. 

      Whenever you need my car, you can take it.

  • You'll tidy up the house and I'll do the shopping. 
       You'll tidy up the house while I do the shopping.

  • You will drop the bomb and it will explode. 
       The moment you drop the bomb, it will explode.

Similarly, other future forms also change to the present simple tense.

  • He is going to leave. The room will be empty. 

      As soon as he leaves, the room will be empty.

  • We are moving next week. Then we'll call you.
       When we move next week, we'll call you.

If we describe an action that is happening at the same time as another future action (the two activities are simultaneous), we use the present continuous tense in time clauses.


  • We are going to cut the grass. You'll pick the apples. 

       While we are cutting the grass, you'll pick the apples.

* The future perfect simple and continuous become the present perfect simple and continuous.


  • I'll have finished my grammar exercises in ten minutes. Then I'll go out. 

      After I have finished my grammar exercises, I'll go out.

  • They will have repaired our car by the weekend. And we will go on a trip. 
      As soon as they have repaired our car, we will go on a trip.
