Time Difference Calculator
Difference between two times of day (handles overnight spans).
Worth Knowing
Finding the gap between two clock times is trickier than it looks because time wraps around at midnight — an interval from 10 PM to 6 AM is eight hours, not minus sixteen. This tool handles that overnight rollover, which is exactly the case manual arithmetic gets wrong. It's the core of timesheet and shift calculations, where a night shift crossing midnight is common and easy to miscount by a full day if the wraparound isn't handled.
