One calendar common year has 365 days: 1 common year = 365 days = (365 days) × (24 hours/day) × (3600 seconds/hour) = 31536000 seconds One calendar leap year has 366 days (occures every 4 years): 1 leap year = 366 days = (366 days) × (24 hours/day) × (3600 seconds/hour) = 31622400 seconds So, we take the 3,600 seconds per hour and multiply it by 24 hours. This gives us 86,400 seconds in a day. Step 4: Calculate the number of days in a non-leap year. In a regular, non-leap year, there are 365 days. So, we take the 86,400 seconds in a day and multiply it by 365 days. This comes out to be 31,536,000 seconds in a non-leap year. Wondering how many seconds are in a year? Learn the exact number of seconds in a regular and leap year, with simple formulas and examples. Quick and easy explanation for students and exam prep! 365 days × 24 hours × 60 minutes × 60 seconds = 31,536,000 seconds. In words, there are thirty one million, five hundred thirty-six thousand seconds in a standard year.
