How to calculate working time

1. Enter the start and end time. In the format hh:mm, for example 08:00 and 16:30.
2. Vähennä tauot. Anna taukojen kokonaiskesto minuutteina.
3. Huomioi yövuoro. Rastita ”työ jatkuu yön yli”, jos vuoro päättyy seuraavana päivänä.
4. Calculate. You get the total time, breaks and net working time in hours and minutes.

In payroll and time tracking, time is often expressed in decimal hours. Minutes are converted to hours by dividing by 60: for example, 15 minutes is 0.25 hours and 135 minutes is 2 hours 15 minutes, i.e. 2.25 hours. The calculator shows both the hours-minutes format and the decimal format, so you can use whatever your employer's system requires.

What can the calculator be used for?

The working time calculator is suited to tracking work hours, filling in timesheets, calculating billable hours and managing flexible working time. The night shift function makes it easier to calculate shift work when a shift starts in the evening and ends in the morning. Because the calculator handles clock times, it computes the times correctly even across midnight.

Example: a shift-work week

Let's calculate the length of one shift. The shift starts at 22:00 and ends at 06:30 the next morning, and includes a 30-minute break. Because the shift continues overnight, the total time is 8 hours 30 minutes. When the 30-minute break is subtracted, the net working time is 8 hours, or 8.00 hours in decimal form. The calculator handles the change of day automatically when you tick the overnight option, so you don't have to count the hours by hand.

Many jobs have flexible working time, where daily hours vary and the difference from the agreed working time accumulates as a balance. If the agreed day is 7.5 hours and you worked 8.25 hours, a balance of 0.75 hours, or 45 minutes, accumulates. Decimal hours make it easier to track the balance because they add up directly. The working time calculator gives the net working time in both hours-minutes and decimal form, so you can compare it with the agreed working time and keep a record of the accumulation.

In working time calculations, confusing clock times with decimals is a common mistake. 8:15 does not mean 8.15 hours but 8.25 hours, because 15 minutes is a quarter of an hour. Time is calculated in a base-60 system, but pay and balances in decimals, so the conversion from minutes to decimals must be done carefully. This calculator handles the conversion automatically and shows both forms side by side.

Workplaces often have their own rounding practices: hours may be rounded to the nearest five or fifteen minutes. It is good to know your own workplace's rule so that the records match payroll. When you calculate the net working time accurately and know the rounding method in use, hour bookkeeping stays clear and disagreements are avoided. Decimal hours also make it easier to add up hours across several days.

সংক্ষেপে

The working time calculator computes the length of a workday including breaks and night shifts and converts minutes into hours. Enter the times and breaks, and you get the net working time in hours, minutes and decimal hours. The overnight option handles the change of day automatically, and decimal hours make it easier to track timesheets and the balance.
