Time Calculator

Calculate the difference between two times in hours and minutes.

🇩🇰 All calculations are based on Danish rules, rates, and currency (DKK). This calculator is translated for convenience but applies exclusively to Denmark.

Time Calculator

This calculator finds the difference between two times, showing the result in both hours-and-minutes format and as a decimal number of hours. It is particularly useful for tracking work hours, calculating overtime, or determining how long a journey or event will take.

Work Time Tracking

In Denmark, the standard full-time work week is 37 hours, typically spread across five days. Many employees track their start and end times to calculate daily hours. If you start at 8:30 and finish at 17:15, this calculator quickly tells you that you have worked 8 hours and 45 minutes, or 8.75 hours in decimal format — useful for timesheet reporting.

Decimal Hours

Many payroll systems and project management tools use decimal hours rather than hours and minutes. In decimal format, 30 minutes is 0.5, 15 minutes is 0.25, and 45 minutes is 0.75. This calculator provides both formats so you can use whichever your system requires. For flex-time (flekstid) tracking, which is common in Danish workplaces, the decimal format makes it easier to add up hours across the week.

Frequently Asked Questions

How do you calculate speed and time?

Speed (v) is a vector measuring displacement (or change in position, Δs, with direction) over change in time (Δt), represented by the equation v = Δs/Δt. Speed as a scalar measures distance traveled (d) over change in time (Δt), represented by the equation speed = d/Δt.

How do you write 2 o'clock at night?

2 AM is written as "2 o'clock at night" in Danish, while 2 PM (14:00) becomes "2 o'clock in the afternoon". Denmark uses the 24-hour clock system in most formal contexts.

How do you convert minutes to hours?

To convert minutes to hours, divide the number of minutes by 60. For example: 90 minutes ÷ 60 = 1.5 hours. To convert hours to minutes, multiply by 60. The decimal format is often used in payroll systems, where 7 hours and 24 minutes is written as 7.4 hours.
