Did you know that while the sun rises to a new day for those in India, the day comes to an end in Australia, while those in the U.S. are still in the day before?
Confusing isn’t it? That is why the concept of Time Zones was developed.
What is it?
The world is divided longitudinally (the North Pole to the South Pole), like slices of a cake. Each line represents a different time zone, with each hour difference roughly 15 degrees apart. There are more than 24 such time zones in the world.
Universal Coordinated Time (UTC) – formerly known as Greenwich Mean Time (GMT) – is the primary time standard by which the world regulates clocks and time. It is based on the imaginary line used to indicate 0° longitude.

Each country or region has its own name for the time zone, which are not part of the international time and date standard.
In India, we follow the Indian Standard Time (IST) based on longitude 82.5°. This longitude passes through Mirzapur, near Allahabad in Uttar Pradesh. It is 5 hours 30 minutes ahead of the UTC. Officially, the IST is indicated as UTC+05:30.
Here’s a challenge for you. Can you find the parts of the names of these time zones (highlighted in blue) in the word grid?
