The query "how many hours between and" is incomplete and lacks the specific times or dates between which the hours need to be calculated. To find the number of hours between two points in time, the start time and end time must be provided. There are several online tools and methods available that can calculate the hours and minutes between two given times or dates. If the user can provide two specific times (e.g., 9 AM and 5 PM) or dates, the exact number of hours between them can be calculated. Otherwise, a general method involves converting times to a 24-hour format and subtracting the start time from the end time. For times that span over midnight, the calculation considers that the end time comes the next day. Please specify the two times or dates to calculate the number of hours between them. If there is a need, I can guide on how to perform the calculation or use an online calculator for it.
