How This Works
This tool finds the elapsed time between two points on the clock. If the end time is earlier than the start time, it assumes the range crosses midnight into the next day (like a night shift), which is the standard convention for time-of-day calculators.
Formula
Elapsed Time = End Time − Start Time
Example
From 9:00 AM to 5:30 PM is 8 hours 30 minutes. From 10:00 PM to 6:00 AM (crossing midnight) is 8 hours.
