What is Year 2000?

Year 2000 was a big problem that computers had to solve when the year changed from 1999 to 2000.

Imagine you have a toy clock that only shows two digits for the year. It reads "99" for 1999, but when it changes, it flips to "00". To your toy clock, that means 1900, not 2000, just like how some old clocks might think "00" is midnight instead of noon.

Many computers worked the same way back then. They used only two digits for the year, so they thought "00" meant 1900, not 2000. This could cause them to do weird things, like adding money incorrectly or stopping altogether!

Some people were worried that all these old computers might crash on January 1, 2000, and the world would go into chaos.

But most of the time, it wasn’t as bad as everyone thought, kind of like how your toy clock might get confused but still keeps ticking along.
