What are modified time zones?

A modified time zone is like a special rule that some places follow so they can have more fun with their day and night times.

Imagine you're playing with your friends in a big park. Most of the park has a simple rule: when the sun goes down, it’s bedtime for everyone. But a small part of the park decides to stay up a little longer, just because they want to play one extra game of tag before going to bed. That smaller part is using a modified time zone.

Normally, places follow the same rules as their neighbors, like how your school follows the same clock as your house. But some places make up their own little rule so they can start or end their day at a different time. For example, some cities in the United States use modified time zones to be half an hour ahead or behind their neighbors.

This is like having a special hour for your favorite video game, you get to play it earlier or later than everyone else, just because you want to!
