How Long Is a Decade? All You Need to Know

Ever wonder how long is a decade? this article gives you all the right answers 

Simple answer to how long is a decade is 10 years. The word comes from the Latin deciens; a decade is made up of ten years. We usually use decades to mean “the last ten years” or “the next ten years.” For example, you could say that you’ve been in your company for five decades. To find out how long a decade is, divide 100 by 10. That gives us the number 10. In a century it is 100 units so 10 decades equals to a century.

Decades are useful for expressing a time span. For example, a person may say that he has been married for three decades. Another example is if a piece of news occurred “over ten years ago.” You can also use decades to describe long periods. For instance, you could say that your child’s been driving for five decades.

How to Write the Decade Correctly

You’d probably want to use decennium instead of the decade in formal writing because it sounds more educated and authoritative. In informal writing, it isn’t a problem which word you use as both have the same meanings and definitions.

It would help if you also were careful when you refer to decades or how long is a decade in conversation. If we think we’re making a point and we’re not, we need to check and make sure that what we’re saying is correct. A good way to check for errors is to use Google’s Ngram Viewer. For instance, we might say, “I went to college in the 90s.” That could mean we graduated in 1999 or we attended college in 1991 and 1992. The Ngram Viewer will show you how frequently an expression has been used over the years. It will also show how often two expressions are used together.

It’s important to understand decade titles such as “the 90s,” “the ’90s,” and “the 2000s.” They can be used as noun or verb forms (like 1990: The 1990s: The 1990s). It’s useful to know them, but you usually don’t need them for most jobs. If you want to cite the decade that someone refers to, you need both the decade and its title.

How to Talk About Time Periods?

There are other ways to talk about time periods. Sometimes people will use the word decade to indicate relative time spans. For instance, if someone says, “This war has lasted for two decades,” it means that the war has been going on for a longer period of time than it should and is more than ten years old.

You want to look at the length of a decade in terms of actual years. If you’re talking about something that happened over more than one decade, such as the 1900s or the 1960s. If you’re talking about an era or period within a decade, such as the 1990s, then you only need to give one year. For example, we might say, “My husband was born in 1975. He grew up in the 90s. “

When you’re talking about a time period that straddles two decades, including both of them, for instance, “I was born in 1980, so I’m coming up on the end of the 1980s.” Another example would be, “I was born in 1977. That makes me part of Generation X.” No matter how many decades are straddled, only one decade should appear at the end. If you’re referring to multiple decades, then it should appear only once at the end.

How to Talk About More Than One Decade?

When referring to time periods or eras separated by more than one decade, it’s common to use ordinal numbers. For instance, someone might refer to the “first decade of the new millennium.”

Studies show that teenagers and young adults can be confused by decades. For example, a teen may mistakenly think that the 1960s ended more than 40 years ago. Most people your age know what you mean by “the 90s “. But it’s important to specify the 90s if you’re talking about anything that happened before 1990 or after 1999.

How to Talk About Time Periods Separated by Decades?

When talking about time periods separated by decades, use ordinal numbers. For instance, “The ’70s, 80’s, and ’90s were a very important era in American history.” You can also say, “The 1970s, 1980s, and 1990s were very important eras in American history. If you want to use the decades correctly, then it’s important to understand which item comes first.

You can also lookup the century in question in the Random House Dictionary. For example, we might say, “We just graduated in 1999. I graduated from college in the 90s.” The Random House dictionary says that the ’90s is commonly used to refer to the decade of the 1990s, and the ’00s is used for referring to the decade of 2000 and later.

What is the Difference Between Decades and Centuries?

A decade baffles definition, and definition bewilders answer. Some believe that at least one needs to be ten years long; others insist that it must span at least 11 years. However, the best definition we have found is that a decade lasts ten years, and anything that spans more than ten years is considered a century. When we extend that to the longer times, we get a very different definition: a Millennia lasts 1,000 years, and anything shorter than this must be considered a century.

Another Meaning for How Long is a Decade

A decade is the number of years that are equal to ten. For example, the decade of the 1990s spanned from January 1, 1990, to December 31, 1999. A decade can have any length of time, depending on how long you want your decade to last. If you choose to make it ten years long, each year will be separated by ten calendar years, making your decade last 100 calendar years. Alternatively, suppose you make your decade 30 days long with every day equivalent in duration with one another. In that case, your 2000th day will correspond to December 31, 2020, while your 3000th day will correspond to December 31, 2030.

Closely related to the decade is the century’s concept, which is 100 years long, so if you divide one century into decades, you will get 10 of them. A decade may also be called age or era, depending on the context in which it is used. For example, the “nineteen-hundreds” was the 1900s decade, and “the last days of the 20th century” was its last year. The first decade of any century is often referred to as a “decade,” even though it spans two centuries (e.g., the 1790s). Roman numerals often represent calendar decades (e.g., the “nineteen-teens” was the 1910s), and its last year is often called “the end of the last decade.”

It may be noted that there could be multiple decades having the same length of time in any given century. For example, there were two decades in the 20th century (1901–2000): the 1900s and the 1990s (and two 18-year long decades: 1801–1810 and 1901–1920). The longest decade in history could be considered to be either.

Theories About Decade

As we age, we start to lose our ability to remember things, including large chunks of time in the past. So when you ask someone how old they were ten years ago or what was happening in their country ten years ago, it’s hard for them to say definitively because their memory starts getting cloudy after around seven years go by.

Another reason we can’t say exactly how long a decade is related to our calendar system. We can’t always say when a decade starts and ends. For example, the ’80s and ’90s in America lasted from 1980 to 1999.

A theory was discovered by scientists in which they talk about how we view the time when we look back on the past and when we look forward to the future. The theory is based on cognitive time travel which involves how we use our memories when we reminisce about the past or think forward to the future. This theory suggests that we view time in chunks or intervals.

What’s the Best Decade for Music?

In terms of music, a decade can span from the 1950s to the 1960s, where most songs were written to match the feelings and interests of that particular time period. They reflected what was going on at that time, such as the Vietnam War and the sexual revolution. The Baby Boomer generation grew up during this exact time period.

The term is also used to describe periods in literature or film wherein similar characteristics are seen even though they were written or produced at different times. The 1920s can be referred to as a decade because it represented a time of the roaring twenties, the prohibition era, and a time where women started to take on more freedoms. The 1960s is also another example of this. The 1960s were a period that reflected a sexual revolution, civil rights movements, and social movements.
