Frequently Asked Questions
How many seconds are in a day?↓
1 day = 24 hours × 60 minutes × 60 seconds = 86,400 seconds.
How many days are in a year?↓
This converter uses the average Julian year = 365.25 days = 31,557,600 seconds, accounting for leap years. A calendar year is exactly 365 days (366 in a leap year).
How many milliseconds are in a second?↓
1 second = 1,000 milliseconds (ms) = 1,000,000 microseconds (µs) = 1,000,000,000 nanoseconds (ns).
How is a month defined in this converter?↓
This converter uses an average month of 30.4375 days (365.25 / 12 = 2,629,800 seconds). Calendar months vary from 28 to 31 days, so this is an approximation for conversion purposes.
