How Many Hours is 9-5?

This tool calculates the total number of hours between 9 AM and 5 PM, which is typically 8 hours.

There are exactly 8 hours between 9 AM and 5 PM on the same day. This duration is very common for a workday. However, the time span is not 8 hours if you want to calculate the hours difference between 9 AM the current day and 5 AM the following day; the duration, in this case, is 20 hours. Similarly, for calculations between 9 AM and 5 PM the following day, the difference is 32 hours.

As you can see, the exact hours between 9 and 5 depend on whether you’re calculating within a single day or across multiple days.
