No, it's actually ever so slightly longer than 24 hours. Days are measured by atomic clocks, instruments that are so accurate that they are more accurate than the spin of the Earth itself. Some days, the Earth will spin 1/5000th of a second faster, but it will never finish in 23 hours, 59 minutes.

Besides, you just said that a day is what 24 hours is equal to. Those arguments contradict each other.
