Answer: 86400

Similarly

How many seconds in a year?

• One astronomical year of a single rotation around the sun has 365.25 days. 

Each day has 86400 seconds, therefore number of seconds in an astronomical year = 365.25×86400=31557600.

• One calendar common year has 365 days

Each day has 86400 seconds therefore number of seconds in a calender common year = 365×86400=31536000.

• One calendar leap year has 366 days (occures every 4 years)

Each day has 86400 seconds therefore number of seconds in a leap year = 366×86400=31622400.
