To calculate how many hours are between a given "am" time and "pm" time, you can follow this general approach:

How to Calculate Hours from AM to PM

1. Identify the AM time and PM time.
   For example, 8:00 AM and 3:00 PM.

2. Convert both times to a 24-hour format (optional but helpful).

   • AM times remain the same (e.g., 8:00 AM = 08:00).
   • PM times add 12 hours (except 12 PM which is 12:00). For example, 3:00 PM = 15:00.

3. Subtract the AM time from the PM time.
   Example: 15:00 - 08:00 = 7 hours.

Example Calculation

• From 9:00 AM to 5:00 PM:
  17:00 - 09:00 = 8 hours.

• From 6:30 AM to 2:15 PM:
  14:15 - 06:30 = 7 hours 45 minutes.

If you provide specific AM and PM times, I can calculate the exact number of hours and minutes for you!
