What Has 4 Letters Sometimes Has 9 But Never 5?

We all know the answer to this riddle is “year.” But why is that? And what are some other interesting facts about years?

Why Does Year Sometimes Have 4 Letters and Sometimes Have 9?

The answer to this question lies in the way we write years. In English, we typically write years using four digits, such as 2023. However, there are some exceptions to this rule. For example, we often write years in the past using only two digits, such as ’68 for 1968. We also sometimes write years in the future using only two digits, such as ’25 for 2025.

So, why do we sometimes write years using four digits and sometimes using only two digits? The answer has to do with the way we keep track of time. We use a system called the Gregorian calendar, which was introduced in 1582. The Gregorian calendar is a solar calendar, which means that it is based on the Earth’s orbit around the sun.

The Gregorian calendar has 365 days in a year. However, every four years, we add an extra day to the calendar to make up for the fact that the Earth’s orbit is not exactly 365 days long. This extra day is called leap day.

Leap years are always divisible by four. So, for example, 2020 was a leap year because it was divisible by four. However, 2021 was not a leap year because it was not divisible by four.

The reason why we sometimes write years using only two digits is because it is a way to save space. When we write a year using only two digits, we can drop the first two digits of the year. For example, instead of writing 2023, we can simply write ’23.

However, there is one important thing to keep in mind when we write years using only two digits. We need to be careful not to confuse them with years that are in the past. For example, if we see the year ’68, we need to know whether it is referring to 1968 or 2068.

To avoid confusion, it is best to always write years using four digits. This will help to ensure that we are always clear about which year we are referring to.
