Trying to figure out how many hours you actually worked, or calculating the duration of that all-night bus trip, can be tedious. This Time Span Calculator removes the frustration. It figures out the exact duration between any two clock times, including those confusing gaps that cross into the next day.

Calculate Time Spans

1. Simple Inputs for Complex Calculations

You only need two times, plus one simple checkbox.

1. Enter Start Time: Choose the time your duration begins, like 8:00 AM (start of work).
2. Enter End Time: Choose the time your duration ends, like 5:30 PM (end of work).
3. Check the Midnight Box: This is crucial. If your end time is earlier than your start time (e.g., you start at 10:00 PM and end at 3:00 AM), check the box labeled End time is next day. The tool assumes the 3:00 AM is the next morning.
4. Click Calculate Time Span: The result shows instantly.

Relatable Fact: Calculating a shift from 11:00 PM to 7:00 AM is where most people fail. They forget to add the extra 24 hours. This tool handles that calculation automatically, especially if you check the midnight box.

2. The Result: All the Details You Need

The result section gives you the total time broken down in three useful formats.

• Hours and Minutes: The simplest breakdown: the main duration displayed in bold blue and green numbers. For example, 8 hours and 30 minutes.
• Total Figures: Below, you get the totals in minutes and seconds. This is great for billing or scientific purposes.
• Decimal Hours: This is the most valuable part for payroll. Instead of 8 hours 30 minutes, you see 8.50 hours. No more converting fractions for timesheets.

If you calculate a span that crosses midnight, a blue info note will appear to confirm the tool used the 24-hour buffer, ensuring your long duration is accurate.
