How Long Is A Decade?
Decades are periods that represent significant milestones in life. They can be marked by birthdays, marriage anniversaries, or even homeownership.
Many people celebrate decades by throwing parties to mark these important events. While some of these celebrations are pretty traditional, there are also a few that have a unique twist to them.
Months
A decade is ten years. It may describe any ten-year period, or it can refer to specific groupings of calendar years.
People often use the word decade to refer to groups of ten years, especially those in the calendar whose last digits run from 0 to 9. But it is also sometimes used to mean any ten years.
One of the big debates about the decade is whether it should be a calendrical term, like century or millennium, or one that’s purely a cultural marker. Some authorities, including Sandi Duncan of the Farmers’ Almanac and Andrew Novick of the National Institute of Standards and Technology, have sided with the former.
“The problem with this is that it’s so confusing,” Novick says. It’s not clear why the public thinks about decades so differently from centuries and millennia, he explains.

Days
A day (the symbol for this unit is d) is the approximate time it takes Earth to complete one rotation around the Sun. In modern times, days are generally considered to be 24 hours long. However, the actual length of a day varies from one year to another because the Sun is not stationary in our solar system.
A decade (from Ancient Greek dekes ‘group of ten’) is ten years. It may be a specific grouping of calendar years, or it can refer to a person’s life.
Hours
A decade is 10 years. An hour is a unit of time equal to 60 minutes, or 3,600 seconds.
The metric system bases its measurements of time upon the second, defined since 1952 in terms of the Earth’s rotation. The hour is a secondary unit computed as precisely 3,600 atomic seconds but may incorporate a positive or negative leap second.
Historically, the hour was taken as one of 24 equal parts of a day (equinoctial hours), and minor variations in the Earth’s rotation caused this unit to be slightly less than a full 24-hour cycle. It was eventually smoothed out by the re-defining of an hour as one of the 24 equal parts of a mean solar day, which is based on astronomical observations.
Minutes
Meeting minutes are written records of meetings that detail what was discussed and how it was decided. Organizations, can act as a reference point for future meetings and help track the success of initiatives and tasks.
They can also serve as a document for accountability if an organization enters into any sort of legal situation. Whether an association is required by law to have minutes or simply wants to make sure they’re available for their members who couldn’t attend the meeting, they can be valuable documents that keep the group in touch and accountable for its actions.
Writing meeting minutes is a vital task for many organizations, especially nonprofits. It’s important to take accurate notes and make sure the information is brief but comprehensive.
Seconds
A second (symbol: s) is the base unit of time in the metric system. It is equal to one millisecond or 1000 milliseconds, prefixed by the standards-base multiplier atto (a).
The second is also used to measure the length of an astronomical day. In astronomy, a day is 86,400 SI seconds.
Converting from decades to seconds involves some math, but it is a simple process. First, you need to know how many years there are in a decade.
Then you need to know how many leap years there are in a decade, which depends on whether the year xx00 is a leap year or not. If there are 2 leap years, there will be an additional 86,400 seconds in a decade. If there are 3 leap years, there will be an additional 172,800 seconds in a decade.
