How Many Seconds Are in a Year?

Here's the calculation for a normal year:

• 60 seconds × 60 minutes = 3,600 seconds in an hour
• 3,600 × 24 hours = 86,400 seconds in a day
• 86,400 × 365 days = 31,536,000 seconds

Related time facts:

• 1 year ≈ 525,600 minutes
• 1 year = 8,760 hours (8,784 in a leap year)
• A quick approximation many people use is that a year is "about π × 10⁷ seconds" (roughly 31.4 million), which is remarkably close.

For an astronomical (solar) year of about 365.25 days, the figure is closer to 31,557,600 seconds.
