To calculate the number of hours between two times given in "PM" format, you can follow these steps:

1. Convert both times to a 24-hour format or just count the hours directly.
2. Subtract the earlier time from the later time.

Example:

• From 2 PM to 7 PM:
  • 7 PM - 2 PM = 5 hours

If you provide the specific times (e.g., 3 PM to 8 PM), I can calculate the exact number of hours for you!
