Seconds in a Year

How many seconds are there in a year?

Hint: You don’t need a calculator

24. If you said 12 for January 2nd, February 2nd, etc that’s close, but you forgot about January 22nd, February 22nd and so on. If you are a math whiz and didn’t need a calculator to perform 60 x 60 x 24 x 365, then 31,536,000 works too. If you used 365.25 to account for leap year, then you are a human calculator, but even that’s not entirely accurate due to the leap second. And even accounting for that, it’s only an approximation that there are 365.2422 days in a year.

How about the second of every month as well as the 22nd of every month adding up to 24 seconds

60 151 992

Could you show your work? I’m not sure where you got that number. If you did the calculation, it would be:

60 (seconds in a minute) x 60 (minutes in an hour) x 24 (hours in a day) x 365 (days in a year) = 31556900, but that doesn’t take into account leap year, or the leap second that’s added once in a while. 365.242 would be closer to the number of days in a year, but I don’t think it’s precise.

But all that aside, this isn’t the answer. Think less of calculations.

How many seconds are there in a year?
31,556,926 seconds or 186000 miles x 31,556,926 seconds = one light-year.

What do you think is the correct answer?

Kevin says

Warren a light year isn’t a measurement of time, it’s a measurement of distance, because of the finite speed light travels at, a light year is the distance that light travels in a year not the time it takes to travel

1yr = 365days, 1day = 24hrs, 1hr = 60minutes, 1minute = 60seconds, .’. 60*60 = 3600 = 24*3600 = 86400, 365days = 86400*365 = 31 536000seconds

Allen says
May 11, 2015 @ 11:04

All of these answers are correct. There are 31,536,000 seconds in a standard year, 31,622,400 seconds in a leap year, approximately 31,556,909 seconds in a solar year. There are also 12 2nd’s (as in dates) in a year, if you choose to count a 22nd as a second (pretty weak, but technically accurate) then there are 24. Just because the questioner had a different response in mind does not change the fact that ALL of the above answers are correct.

To figure it out you would do 365days×24h×60min.×60 seconds soooo it would be 31,536,000

24 seconds

Garth says
July 23, 2015 @ 00:39

I tend to work things out in my head by multiplying by an easier number that will get me close, then working from there.

I started from the number of seconds in a day, 86,400, then multiplied that in stages to get to 375 days, and so on.
86,400 x 5 = 432,000
432,000 x 5 = 2,160,000
2,160,000 x 5 = 10,800,000
10,800,000 x 3 = 32,400,000
32,400,000 – 864,000 = 31,536,000
31,536,000 + 21,600 = 31,557,600.

Dan says
July 23, 2015 @ 01:44

What about accounting for a leap year? :)

Garth says
July 23, 2015 @ 19:37

That’s where the 21,600 at the end comes in.
If you meant the .242 value for the overrun, then subtract (0.008 x 86,400), or (8 x 86.4).
31,557,600 – 691.2 = 31,556,908.8
If you meant the days in an actual leap year, then (31,536,000 + 86,400) = 31,622,400.

what percent of a year is 26 seconds? Obviously I am NOT so great with math :/
I know there is 31,556,926 seconds in a year so would I than divide 31,556,926*12= ??
Or is that the wrong way to set up the problem?? Thanks to anyone with insight!!

Whart says
January 25, 2016 @ 19:47

The question was how many (seconds) not (nd’s) in a year so the correct answer is 31,536,000 in a year.

ome people believe that life is not about how many breaths you take, but instead how many moments take your breath away. What’s for certain is that the time we have is precious. Spend some time today with those you love.

Seconds tick by and turn into minutes. Minutes turn into hours, and hours turn into days. The days turn into years and, before you know it, time has flown by.

Have you ever made a split-second decision? You were going to do X, but then…at the last second…you changed your mind and did Y instead. Maybe it was choosing the path less traveled instead of the wide road. Whatever the reason, mere seconds can be well spent and change lives forever.

Have you ever stopped to consider how many seconds you have? If every second counts, then let’s count the seconds we have. For example, how many seconds do we have in a day? A month? A whole year?

A wise man once said that there are 12 seconds in a year. January 2nd, February 2nd, March 2nd…OK, you get the picture. But those aren’t the seconds we’re talking about! We mean that small unit of time that’s about as long as it takes to say, “one thousand one.”

To figure out how many seconds there are in a year, we’re going to need to know a little math. To convert a certain quantity to a different unit of measure, we need to figure out what is called the conversion factor.

To do this, we need to come up with a ratio — or fraction — that equals one. In the ratio, the conversion factor is a multiplier that gets applied to the larger unit to convert it into the smaller unit through multiplication.

Sound confusing? Don’t worry. A simple example will make things clear. When thinking about how many seconds there are in a year, let’s first figure out the different units of measurement of time involved. We have the second, the minute, the hour, the day, the month and the year.

Let’s start with the largest of these measures: the year. To convert years to the next smallest unit — the month — we have to know how many months are in a year. Since we know there are 12 months in a year, our ratio would be 1:12 (one year:12 months) or 1/12. So, the conversion factor is 12.

If we want to know how many months are in 5 years, we just need to multiply the number of years by the conversion factor. Five years times 12 months/year equals 60 months in 5 years. Easy enough, right?

To figure out even smaller units, you can keep doing multiple conversions to smaller and smaller units. Just make sure that the units you’re using are all the same. For example, there are 24 hours in each day, but not all months have the same number of days. To convert one year to seconds, you’ll need to skip using months and convert to days, hours, minutes and finally seconds.

Each step of the way, you’ll need to compute the conversion factor and then multiply. Here’s what the conversion from one year to seconds would look like:

1 year = 365 days (no, we’re not counting leap years!)

1 day = 24 hours

1 hour = 60 minutes

1 minute = 60 seconds

So…drum roll, please…one year would equal 365 times 24 times 60 times 60 seconds…or 31,536,000 seconds! That’s over 31 million seconds you have to spend over the next year. What will you do with YOUR seconds?

Ready to put some of your precious seconds to good use? Check out these fun ways to spend quality time together as a family:

Play some fun Backyard Games! Watch those seconds turn into minutes and then into hours as you play fun games with your friends and family members right in your own backyard. Time spent with friends and family is always time well spent, so find a game that you can all enjoy and play the day away!Playing games isn’t the only way to have a fun time with friends and family. Why not become tourists in your own city? Have you seen all there is to see in your local area? There always seem to be those little places that you never seem to get around to visiting. Find a new place to explore today. Or you could also make a family meal together! Have all family members think of their favorite food that they’d like to share with everyone else. Head out to the grocery store together and get all the supplies you’ll need. When you get home, turn on some music and get cooking in the kitchen. Enjoy your time together. You’ll have a feast you won’t soon forget! After you’re finished eating, why not end the day by having a family reading party in bed?! Bake some cookies, grab a glass of milk and snuggle up together to read some of your favorite stories together.Up for a challenge? Units of time aren’t the only units of measurement that you can learn to convert from smaller to larger units and vice versa. Head to the kitchen and get out a set of measuring cups and spoons. Using these items, experiment on your own to figure out how the units convert from one to another. How many teaspoons are in a tablespoon? Feel free to use the Internet to research conversion tables for these units of measurement to determine whether your best guesses were accurate or not.

If you are a math whiz and didn’t need a calculator to perform 60 x 60 x 24 x 365, then 31,536,000 works too. If you used 365.25 to account for leap year, then you are a human calculator.

Hudges says
September 26, 2016 @ 07:08

If the question is as written, then it is, as highlighted by Whart above, literally the number of seconds

“The question was how many (seconds) not (nd’s) in a year so the correct answer is 31,536,000 in a year.”

However, should it be spoken in a quiz, then there are several answers as displayed above, but which could also include the second:
– month of the year
– week of the year
– fortnight of the year
– quarter of the year
– half of the year

Should one become pedantic, one might include second halves of matches; football, rugby etc., so the number could be any one of a wide variety of answers, which probably makes this not a very good question. I know that it is supposed to be a little ambiguous, but it leaves too much room for debate.

November 27, 2016 @ 12:25

there are 31,536,000 in a year. To prove it right 1year=365days 1day=24 hours 1hour =60 minutes 1minute=60 seconds therefore 365x24x60x60=31,536,000 seconds i a year. To prove it, use your calculator and calculate it u will find out de same thing or if u dont find the same thing, u made mistake in your calculations.

My question was simple it wasn’t about dates it was about fractions of minutes seconds 3156000 was the answer to my question. How many of these seconds in a year have we wasted. And thinking of it now how many really continue to waste. For me not another single one second for life is so precious and time it’s so precious. To waste any more would be selfish and stupid as for me never again this simple question answered a lot more answers that I needed to hear

The closest answer would be in accordance with the tropical year, natural year and 3 others. Rounding to the nearest second the calculation would include 365 days, 5hours, 48 minutes, 46 seconds or 60 x 60 x 24 x 365.25 -(60 x 12 +46

Superwhiz Maths Person (also neutral as to not offend those who have a complex of themselves and others) says
March 10, 2018 @ 19:52

This is a very technical question, and calls for the most intelligent of minds to decipher it. No lowly creatures below myself could satisfactorily answer this correctly.

As for the person who said “they said seconds, not nds” I dont know of a single day that has twenty two nds in it.
The problem here is that due to scientific technical bull and political correctiveness, we cant really call them seconds as over time, time has changed. This would discriminate against the seconds of the 1800s to now, especially since the world is slowing down in its spin. This demonstrates that over time the speed could have been faster or slower when we werent around. So a more specific question needs to be asked, such as “How many seconds are there in the year 2018?”.
This year so far I have had plenty of seconds. Why last night I had two plates of spaghetti. Id estimate that a year has enough seconds in it to feed a third world country.
This being said it demonstrates that a second can be a measurement of food as well as a measurement of time…or distance as one strange creature described it although this would be a secondary second by definition.
Another instance of seconds would be in meetings, where people pass motions and another seconds the motion. I call that a gastric issue, probably revolving around the initial seconds as formerly mentioned. The more motions passed, it seems that there are more who want to second those motions, which means that there are a lot of motions to seconds. I believe there are more motions to seconds, as not every motion is seconded, so a tangential question could be “How many motions are there in a year…sorry, in the year 2018?”.

bob says
March 30, 2018 @ 12:08

31,536,000 is my answer because 60 seconds are in a minute and 60 minutes are in an hour so I multiplied 60 times 60 and multiplied that number by 24 and multiplied that by 365 and got 31,536,000

Jerry says
May 16, 2018 @ 18:29

how many seconds in a year? well there are a LOT of seconds. for example there you can have seconds on ice cream (yumm). and there will be runner ups in races, but they will be in second. and if i am the vice president and i agree with the president then i can second his or her statement. and lastly there are seconds in a minute. and also seconds of the month. so all of u are wrong, there are 5 seconds in a year.

Mohamed says
March 4, 2021 @ 18:36

The answer could be 12 seconds like January 2nd February 2nd…and so on.
Or 24 since there’s 22nd.
Or (60*60*24*365)+(6*60*60)=31557600
6*60*60=6 hours in every year bc 24h is added in every 4 years which gives February 29th 👏👏applause please!!
