Changing the clocks....
When we change the clocks in spring our evenings are lighter for longer which is very nice - but my toddler still wakes me up too early in the morning, even though it was darker today at 6.30am than it was last week.
Up until the coming of the railways in the UK, people kept time by looking at the sun and the stars. We used sundials to measure the shadow of the sun. In a relatively small country there weren't too many inconsistencies as the sun rises and sets at more or less the same time across the country. In 1880 GMT was adopted across the UK - which stands for Greenwich Mean Time.
The Greenwich Meridian is marked on the ground at the Royal Observatory in Greenwich, south-east London. From this point time can be measured relative from one set place on the earth.
While we're on the subject of clocks - can anyone identify these three famous clocks?
Do you change your clocks every year? Why? Do people mind changing their clocks? I'd like to know how it works in large countries which have wide geographical areas but don't change their time zones. Does that mean you always wake up in the dark and always go to bed while its light at certain times of year? In the United States it's called Daylight Savings time. What do you call it? How would you translate it into English?
Some of the words and phrases we've come across today:
toddler - child aged 1-3 years old, has recently learned to walk
sundials - instruments which measure the time by the position of the sun
inconsistencies - here, differences
Meridian - an imaginary vertical line across the earth from north to south pole
