Everything is calculated in your browser: no data is sent anywhere. Indicative result: the applicable collective agreement and your payroll consultant have the final word.
How the calculation works
- 1 Each time is turned into minutes: hours × 60 + minutes. 7:45 is 465 minutes.
- 2 Times with a minus sign are subtracted, the others are added. The total in minutes is turned back into hours and minutes.
- 3 Decimal hours divide the minutes by 60: 9 hours 30 minutes is 9.50. Never add hours and minutes as if they were decimals: 7:45 plus 0:30 is 8:15, not 7:75.
Frequently asked questions
How do you add hours and minutes?
Turn them into minutes, add them up and turn the total back into hours and minutes. 7:45 plus 2:30 is 10:15.
How do you subtract them?
Write the time with a minus sign, for example -0:45: it is taken off the total. If the result is negative, a minus sign appears.
Why is the total also in decimal hours?
