Well it really depends what you mean. By the Gregarian calendar, it is supposed to be exactly 24 hours (the leap year makes up for the extra time). In regard to the sun, since there are 365.2425 days in a year, a day is 24.0159 (approx) hours. In regard to the stars, we actually move faster...so there are only about 23.9 hours in a day.
Its all relative.

a day is the time it takes for the earth to rotate around the sun..
It is 23 hrs and 56 minutes..
and the reason we have leap years is because an actual full rotation is 365.25 days so instead of getting a new calender on a .25 day we just say its one whole day every 4 years..

A day, in the Gregorian calendar, is defined as exactly 86,400 seconds. That equals exactly 1440 minutes, or 24 hours.
The average length of a year in the Gregorian calendar is 365.2425 days.

A YEAR is the time it takes the Earth to go around the sun, a DAY is the time it takes to make a full rotation on the axis.

24 hours or 2400 hours now you can add the minutes and seconds.
