Formula Used

The Hours Calculator determines the time difference in minutes, then converts it to hours and minutes:

• Convert to 24-hour format: AM/PM times are converted to a 24-hour format for consistent calculations.
• Total Minutes: Calculate the difference between the start and end times in minutes.
• Date Adjustment: If dates are included, add the total minutes for each day in the range (24 hours = 1440 minutes per day).
• Convert to Hours and Minutes: Divide the total minutes by 60 to find hours, and use the remainder as minutes.

Frequently Asked Questions (FAQ)

What happens if I don’t enter a date?

If no dates are provided, the calculator assumes the times are on the same day. If the start time is after the end time, it assumes the end time is on the next day.

Can I calculate hours across multiple days?

Yes, simply enter the start and end dates. The calculator will account for the full 24-hour cycles between the dates.

What happens if I enter invalid times?

The calculator will alert you to enter valid hours (1-12) and minutes (0-59).

Does the swap function reset my inputs?

No, the "Swap Times" button only switches the values of the start and end times, leaving other fields intact.

Can I calculate the total duration in seconds?

Currently, the results are displayed in hours and minutes. For seconds, multiply the total minutes by 60.

Tips for Best Results

• Double-check the AM/PM selection to ensure accurate calculations.
• Use the date fields for calculations that span multiple days.
• Click "Swap Times" for a quick way to reverse start and end times without retyping.
• Clear the inputs between calculations to avoid errors.
