Working Time Calculator
Calculate your working time per day, week, month and year – including workdays, breaks, vacation and public holidays.
Calculate now
Use this working time calculator to determine your daily, weekly, monthly and yearly working time based on start time, end time and break. It also shows how many effective working hours remain per year after vacation and public holidays. This is especially useful for full-time jobs, part-time work, flexible models, shift planning and job comparisons.
Working Time Calculator: Track working time, breaks and time balance cleanly
Everyday calculators help make quick decisions more reliably. The right unit, period and base value are essential.
How to use the result better
- Clarify the base value first.
- Check unit and period: per day, month, year, net or gross.
- Calculate a second variant for plausibility.
Common mistake
Many errors come from swapped base values, mixed units or wrong periods. The result may look correct but answer the wrong question.
What to check next
Use related calculators if you want to put the result into money, time, percentages or deadlines.
Why is the unit so important?
A wrong unit or period immediately changes the result and can lead to wrong decisions.
How can I quickly check the result?
Calculate a second variant or estimate roughly in your head. Large differences become easier to spot.

How the result is calculated
Gross working time per day = end time − start time
Net working time per day = gross working time − break
Weekly working time = net working time per day × working days per week
Monthly working time = weekly working time × 52 ÷ 12
Working days per year = working days per week × 52 − vacation days − public holidays
Net annual working time = net working time per day × working days per year
Worked example
Example: You work from 08:00 to 17:00 with a 30-minute break, 5 days per week, 30 vacation days and 10 public holidays. This results in 9.00 gross working hours per day and 8.50 net working hours per day. Based on that, the calculator determines your weekly, monthly and annual working time as well as your effective working days per year.
What is a working time calculator useful for?
A working time calculator helps you understand how many hours you actually work per day, week, month and year. This is useful when comparing contracts, evaluating part-time offers, planning home-office schedules, student jobs or side jobs.
Why are breaks important?
Breaks are not always part of paid net working time. That is why the calculator separates gross working time from net working time. This makes it easy to see how fixed breaks affect your real working hours.
How are vacation days and public holidays included?
Vacation days and public holidays reduce the number of days you actually work during the year. This gives a more realistic picture of annual working time and is especially useful for salary comparisons, hourly-wage estimates and personal planning.
Which result metrics are especially useful?
The most useful outputs are not only daily net hours, but also weekly and monthly hours, effective working days per year, annual break time and the number of real working weeks. Together these metrics provide a much more useful picture of your working model.
Who is this calculator for?
The calculator is suitable for full-time employees, part-time workers, students, mini-job arrangements, flexible schedules and many everyday working-time questions. It can also serve as a simple orientation for shifts that cross midnight.
How to use the result correctly
Use the calculator for planning, comparison and orientation. For legally binding working-time issues, payroll, contracts or formal time tracking, always rely on your employment contract, company rules and professional advice where needed.
Frequently asked questions
How do I calculate my daily working hours?
Subtract start time from end time and then subtract the break. This calculator does that automatically.
Does the calculator show gross or net working time?
Both. You get total attendance time per day and net working time after deducting the break.
Can I use it for part-time work?
Yes. The calculator works well for part-time models because you can enter workdays per week, breaks and daily times flexibly.
Why is annual working time lower than 52 full weeks?
Because vacation days and public holidays are subtracted from the potential working days, producing a more realistic annual total.
Can I calculate overtime with it?
Not precisely. This calculator is mainly designed for standard working schedules. Exact overtime calculations need additional rules and data.
Is the result legally binding?
No. The calculator is for general information and first orientation only. Your contract, time-tracking records and professional advice remain the relevant sources.
