To find out how many seconds are in a year, you can calculate it step-by-step:

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

So, there are 31,536,000 seconds in a common (non-leap) year.

For a Leap Year (366 days):

• 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 to be even more precise, accounting for leap seconds and other variations, the number can vary slightly, but this is the standard calculation.
