1. The problem asks us to subtract two dates and express the difference in hours. 2. To do this, first find the difference in days between the two dates. 3. Then, convert that difference into hours by multiplying by 24 (since 1 day = 24 hours). 4. For example, if the difference between the dates is $d$ days, then hours difference $= d \times 24$. 5. Without specific dates given, the formula to find hours between two dates date1 and date2 is: $$\text{Hours} = |\text{date2} - \text{date1}| \times 24$$ 6. This absolute value ensures the result is positive regardless of which date is earlier.
