🧮 Example: How to Calculate Time Spent
Let’s go through a few examples.
Example 1: Workday Duration
- Start Time: 9:00 AM
- End Time: 5:00 PM
✅ Result: 8 hours 0 minutes
Example 2: Study Session
- Start Time: 2:15 PM
- End Time: 4:45 PM
✅ Result: 2 hours 30 minutes
Example 3: Overnight Shift
- Start Time: 10:00 PM
- End Time: 6:00 AM
✅ Result: 8 hours 0 minutes
The calculator automatically handles overnight sessions by assuming the end time is on the next day — ensuring accurate results no matter when you start or finish.
📊 Formula Used in the Time Spent Calculator
The Time Spent Calculator uses a universal time subtraction formula: Time Spent=End Time−Start Time\text{Time Spent} = \text{End Time} – \text{Start Time}Time Spent=End Time−Start Time
If the end time occurs before the start time (e.g., crossing midnight), it automatically adds 24 hours to ensure a correct duration.
Example:
Start Time = 22:00 (10:00 PM)
End Time = 04:00 (4:00 AM next day) (24+4)−22=6 hours(24 + 4) – 22 = 6 \text{ hours}(24+4)−22=6 hours
✅ Result: 6 hours
