Who is Greenwich Mean Time?

Greenwich Mean Time is like a clock that everyone on Earth agrees to use so they can all know what time it is at the same moment.

Imagine you and your friends are playing a game around the world, but each of you has your own clock. Some say it's 10 o’clock, others say 3 o’clock, it’s confusing! That’s why we need Greenwich Mean Time, which acts like a leader clock for all of us.

Greenwich Mean Time comes from a place called Greenwich, near London. It's like the starting line in a race, everyone else lines up based on where they are, but they all check their time against this one special clock.

Think of it as the sun’s favorite spot, when the sun is directly above Greenwich, that’s 12 o’clock there. And from that moment, we can figure out what time it is anywhere else in the world.

So next time you see a time zone map or set your watch for a trip, remember: it all started with a clock at Greenwich!
