Example Calculation

Let’s see a practical example:

  • Start Time: 09:30
  • Duration: 6:45 (6 hours and 45 minutes)

Step 1: Convert start time and duration to minutes:

  • Start Time = 9 × 60 + 30 = 570 minutes
  • Duration = 6 × 60 + 45 = 405 minutes

Step 2: Add the minutes together:

  • Total Minutes = 570 + 405 = 975 minutes

Step 3: Convert total minutes back to 24-hour time:

  • End Hours = floor(975 ÷ 60) % 24 = 16
  • End Minutes = 975 % 60 = 15

Result:

  • End Time: 16:15
  • Total Minutes: 975

This example illustrates how the calculator quickly handles time addition without confusion.
