Daylight saving time in the United States

Most of the United States plays a game with the sun by changing its clocks! It's like a big country-wide experiment. But some places, like Hawaii and Arizona, don't join in. They like to keep their clocks the same all year round. It's like some kids get to stay up later for a special party, while others have their usual bedtime!

This clock-changing game started a long, long time ago. In 1966, grown-ups decided to make a rule for everyone who wanted to play. It's called the Uniform Time Act. This act helped make sure everyone who changed their clocks did it the same way. It's like when your teacher makes sure everyone in class uses the same crayons for a drawing!

Twice a year, we play a game with our clocks. In the spring, we 'spring forward,' which means we move our clocks one hour ahead. So, 2:00 a.m. becomes 3:00 a.m.! Then, in the fall, we 'fall back,' moving our clocks one hour behind. 2:00 a.m. becomes 1:00 a.m. again! This means we get more sunshine in the evening during the warmer months.

The main idea is to get more sunshine in the evening when it's warmer. Imagine playing on the playground for an extra hour after school! This helps people do more fun things outside. It's like having a bonus playtime! Most of the country does this for about 65% of the year, which is a super long time!
