What does this calculator do?
Use this working time calculator to estimate your daily, weekly, monthly and annual working hours from start time, end time and break duration. It also shows how many effective working hours remain per year after vacation days and public holidays are considered. This is useful for full-time work, part-time work, flexible schedules and job comparisons.
Formula
Gross working time per day = end time − start time\nNet working time per day = gross working time − break\nWeekly working time = net working time per day × working days per week\nMonthly working time = weekly working time × 52 ÷ 12\nWorking days per year = working days per week × 52 − vacation days − public holidays\nNet annual working time = net working time per day × working days per year
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 a gross working time of 9.00 hours per day and a net working time of 8.50 hours per day. The calculator then derives your weekly, monthly and annual working hours.
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 and hourly-wage estimates.
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 is intentionally simple so you get a result quickly.

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.
