It sounds like you have been able to counts seconds correctly. Do the same thing - use an external AND gate to reset the hours counter string to zero when the count = 24.

There are several types of asynchronous counters - some in binary and others with BCD outputs. There are also several different logic families. It helps to be specific about these things when asking for help.
First comes the hardware, then the software.
