 # How Many Seconds Are In A Year (Calculation Solved)

Working out how many seconds in a year is highly beneficial for factories that have machines running 24 hours a day 365 days a year, producing several items a second. Indeed, financial companies on the New York & London stock exchange wish to know how many second they have or hours every day to execute financial transactions.

## Common year calendar seconds in a year

Each common year is 365 days on standard calendar time period divided into 12 months, weeks, days, hours and seconds.

Identify and calculate unit measurements that make up one common calendar year of 365 days.

365 days = 1 common year
24 hours = 1 day
60 minutes = 1 hour
60 seconds = 1 minute

Formula 1 year in seconds = (seconds in a minute) x (minutes in an hour) x (hours in a day) x (days in a year)

60 (seconds/minute) x 60 (minutes/hour) x 24 (hours/day) x 365 (days/year) = 31,536,000 seconds in a year. (Common year)

## Alternative calculation method

Multiply number of seconds in a day x days in a common year

60 seconds x 60 minutes x 24 hours = 86,400 seconds in a day

Seconds in day 86,400 x 365 day in a year = 1 year in seconds

## Leap year seconds in a year

Leap Year =366 days,   24 hours/day,     60 minutes/hour,     60 seconds minutes

Work out seconds a minute 60 x 60 =3,600 seconds in a minute

(366 days) × (24 hours/day) × (3600 seconds/hour) = 31622400 seconds in a leap year.

## Solar year

1 solar year is 365 days 5 hours 48 minutes and 46 seconds, although varies by up to 30 seconds each year, time taken for the earth to circle the sun.

Solar year calculation

365 days (365 x 24 x 60 minutes) = 525,600 minutes

5 hours (5 x 60) = 300 minutes

48 minutes = 48 minutes

46 seconds = 46/60 minutes = 0.76666 of a minute

Minutes (525,600 + 300 + 48 x 60 seconds) + 46 seconds = 31,556,926 seconds in solar year approximately.

How many seconds in a week?

7 days = 1 week

24 hours = 1 day

60 minutes = 1 hour

60 seconds = 1 minute

Formula: days 7 x 24 hours x 60 minutes x 60 seconds = 604,800 seconds in a week

Or

1 hour = 60 x 60 = 3,600 sec,  1 day = 3600 x 24 = 86,400,  1 week = 86400 x 7 = 604,800 seconds in a week
