To calculate how many seconds are in a year, we need to consider whether it's a common year or a leap year.

Calculation for a Common Year (365 days)

• 1 minute = 60 seconds
• 1 hour = 60 minutes = 60 × 60 = 3,600 seconds
• 1 day = 24 hours = 24 × 3,600 = 86,400 seconds
• 1 year (365 days) = 365 × 86,400 = 31,536,000 seconds

Calculation for a Leap Year (366 days)

• 1 leap year = 366 × 86,400 = 31,622,400 seconds

Summary:

Year Type| Seconds in a Year
---|---
Common Year| 31,536,000 seconds
Leap Year| 31,622,400 seconds

If you want a rough average accounting for leap years every 4 years, you can use: Average year length = 365.25 days

• 365.25 × 86,400 = 31,557,600 seconds
