Time Differences Worksheets
How to Calculate Time Differences - Calculating time is easy, right? But what to do when you are stuck with calculating time differences? Well, let's make it easy! There are 360 imaginary lines that are running vertically across the poles of the Earth. These lines are known as longitudes or meridians. Each of this longitude is known as a degree. The longitude that passes through Greenwich, near London, is 0 degree and is considered as the standard time zone. The time zones for all other zones are also calculated through the Greenwich time zone accordingly. The difference between each time is almost four minutes. So when it is noon in Greenwich, the time at 1 degree would be 12:04. Just like this, the standard meridian in India is 82 and a half degrees so the time difference between the two longitudes is 82. When you multiply the number by four, you will get 330 minutes, which is 5 hours and 30 minutes. This selection of worksheets and lessons help students learn to measure the amount of time between fixed times.
