Time Duration Calculator

About the Time Duration Calculator

The Time Duration Calculator computes the difference between two times, providing the duration in days, hours, minutes, and optionally seconds.

Time Duration: Calculated by converting times to 24-hour format and finding the difference.

Use this tool for scheduling, project planning, or tracking time intervals.

• Features:
  • Calculates duration between two times.
  • Inputs: Start Time (hours, minutes, AM/PM), End Time (hours, minutes, AM/PM), optional seconds.
  • Keypad includes digits (0–9) and colon (:) for time formatting.
  • Displays calculations in LaTeX format using MathJax.
  • Clear, backspace, and copy functionality for results.
  • Share or embed the calculator.
• Practical Applications: Useful for project managers, event planners, or anyone needing to calculate time intervals.
• How to Use:
  • Enter Start Time (hours 1–12, minutes 0–59, AM/PM).
  • Enter End Time (hours 1–12, minutes 0–59, AM/PM).
  • Check "Include Seconds" for precise calculations and enter seconds (0–59).
  • Use the keypad to input digits or colons (e.g., 12:30).
  • Click "Calculate" to view the duration and note.
  • Use "Clear" to reset or "⌫" to delete the last character.
  • Copy results or share/embed the calculator.
• Helpful Tips:
  • Hours must be 1–12, minutes and seconds 0–59.
  • End time must be after start time for positive duration.
  • Use colons for time format (e.g., 12:30).
  • Enable seconds for high-precision needs (e.g., scientific experiments).
  • Results include days if the duration exceeds 24 hours.
• Examples:
  • Example 1:
    • Inputs: Start Time = 9:00 AM, End Time = 5:00 PM
    • Calculation: 17:00 - 9:00 = 8 hours
    • Result: Duration = 8 hours, Note: Equivalent to a standard workday.
  • Example 2:
    • Inputs: Start Time = 11:30 PM, End Time = 2:45 AM (next day), Include Seconds
    • Calculation: (24:00 + 2:45:00) - 23:30:00 = 3:15:00
    • Result: Duration = 3 hours, 15 minutes, Note: Total duration is 3.25 hours.
