How Many Hours In A Year?

It might seem easy to calculate the number of hours in a year, but it can be a bit tricky with the regular year, leap year, and different types of years. To put it simply, there are 8,760 hours in a year; however, there are different types of years that can make that amount more or less.

Hours in a Year

In most of the world, we use the Gregorian Calendar which has 365.2425 days in a year. It uses the common year (365 days), then a leap year (366 days) every four years to keep its calculation right. In a common year, there are 8,760 hours and in a leap year, there are 8,784 hours.

Hours in a Day x Days in a Year = Hours in a Year

  • 1 Common Year: 24 hours per day x 365 days = 8,760 hours
  • 1 Leap Year: 24 hours per day x 366 days = 8,784 hours

There are also various other types of years. The Julian calendar was used before the Gregorian calendar; however, it was inaccurate and overestimated the year length by 11 minutes 14 seconds. There is also a sidereal year (which is the actual time it takes the Earth to make a rotation around the Sun), the tropical year (or the year of the seasons), and others.

Hours in a Day, Week, Month, & Year

Let’s take a look at some other units of time. We already know that there are 24 hours in a day. That means there are 168 hours in a week. To find out how many hours are in a week you would calculate:

Hours in a Day x Days in a Week = Hours in a Week

  • 1 Day: 24 hours
  • 1 Week: 24 hours x 7 days per week = 168 hours

Using a similar calculation, you can figure out the days in a month. However, remember that each month has a different amount of days, and February has an extra day in a leap year. That’s why the hours in a month range from 672 hours to 744 hours. 

Hours in a Day x Days in a Month = Hours in a Month

  • 1 Month: 24 hours x (28-31) days = 672 – 744 hours
    • 28 days= 672 hours
    • 29 days= 696 hours
    • 30 days= 720 hours 
    • 31 days= 744 hours

If you only took the hours in a year 8,760 and tried to divide it equally into 12 months to get 730 hours, that would be wrong.

Hours in a Leap Year8784

Minutes in a Day, Week, Month, & Year

How about we take it a step further and see what the conversion is to minutes? There are 60 minutes in an hour. Since there are 24 hours in a day, there are 1,440 minutes in a day.

Minutes in an Hour x Hours in a Day = Minutes in a Day

  • 1 Hour: 60 minutes
  • 1 Day: 60 minutes x 24 hours per day = 1,440 minutes

There are 4,032 minutes in a week. To find out how many hours are in a week you would calculate:

Minutes in an Hour x Hours in a Week = Minutes in a Week

  • 1 Week: 60 minutes x 168 hours per week = 1080 hours

Using a similar calculation, you can figure out the days in a month. However, remember that each month has a different amount of days, and February has an extra day in a leap year. Therefore, the minutes in a month range from 40,320 minutes to 44,640 minutes.

Minutes in an Hour x Hours in a Month = Hours in a Month

  • 1 Month: 60 minutes x (672-744) hours per month = 40,320 – 44,640
    • 28 days (672 hours)= 40,320
    • 29 days (696 hours)= 41,760
    • 30 days (720 hours)= 43,200
    • 31 days (744 hours)= 44,640

If there are 8,760 hours in a year, then there are 525,600 minutes in a year.

 Minutes in an Hour x Hours in a Year = Minutes in a Year

  • 1 Common Year: 60 minutes per hour x 8,760 hours = 525,600
  • 1 Leap Year: 60 minutes per hour x 8,784 hours = 527,040
Minutes in a Year525,600
Minutes in a Leap Year527,040
Minutes in a Month40,320 to 44,640
