Most of the world changes their clocks twice a year, once in the spring and once in the fall. This has been a long tradition that has been followed for many years. There are a few reasons why we have to change our clocks twice a year.
The main reason is because the Earth’s orbit around the sun is not exactly 365 days. It’s actually about 365.24 days. This means that over the course of a year, the seasons will change very slightly. In the spring, the days start to get longer because the Earth is closer to the sun. In the fall, the days start to get shorter because the Earth is further away from the sun.
If we didn’t change our clocks, then the days would eventually get out of sync with the seasons. In the summer, it would stay light out until 10 PM, and in the winter it would get dark at 4 PM. This would be very confusing and it would be hard to know when to start and end the day.
Changing the clocks twice a year helps to keep the days in sync with the seasons. In the spring, we move the clocks ahead one hour so that it stays light out for longer. In the fall, we move the clocks back one hour so that it gets dark earlier.
There are a few other reasons why we change our clocks twice a year. One reason is because it saves energy. In the summer, when it stays light out longer, we don’t need to use as much artificial light. In the winter, when it gets dark earlier, we can use less artificial light and save energy.
Another reason to change the clocks is because it can help prevent traffic accidents. In the fall, when the clocks are turned back one hour, it gets dark earlier and this can lead to more accidents because people are driving home from work in the dark. In the spring, when the clocks are turned ahead one hour, it stays light out for longer and this can help to prevent accidents because people are more likely to be able to see in the light.
Changing the clocks twice a year is a tradition that has been followed for many years. It helps to keep the days in sync with the seasons and it can also help to save energy and prevent traffic accidents.
