Work Hours & Days Calculator

Work Hours & Days Calculator helps you calculate work hours, work days and estimated pay without switching between a calendar, notes and a calculator.

Enter your start time, end time and break time to calculate your actual work time by the minute. Add an hourly wage to check your estimated pay for the shift. You can also calculate how many work days are included in a date range by selecting the days of the week you work.

Save your calculated work time to the built-in calendar and review your monthly total work days, total work hours and estimated pay at a glance. It is useful for part-time workers, freelancers, hourly workers, project work and anyone who needs a simple manual work log.

1. Work hours calculator
Select your start time and end time, enter your break time, and calculate actual hours worked. It is a simple way to check daily work time after unpaid breaks are deducted.

2. Work days calculator
Choose a start date, end date and work weekdays to calculate total work days for that period. Use it for weekday schedules, selected weekdays, part-time schedules or project periods.

3. Hourly wage and estimated pay
Enter your hourly wage to calculate estimated pay from your work time. Check how much you may have earned for the day or review your estimated monthly pay from saved records.

4. Calendar work log
Save work records to the calendar and review each day later. Add a memo when you need to keep notes about a shift, task, workplace or special detail.

5. Monthly summary
The calendar records are summarized into monthly total work days, total work hours, total estimated pay and average daily work time. This helps you review your timesheet before payday or month-end planning.

6. Overnight shifts and previous values
If an end time is earlier than the start time, the app treats it as an overnight shift and calculates the end time as the next day. You can also load previous start time, end time, break time and hourly wage values to reduce repeated input.

Recommended for:
Part-time workers who calculate hours and pay manually
Freelancers and project workers who need a simple work log
Hourly workers who want to calculate work time after breaks
People who count work days for a selected date range
Anyone who wants a calendar-based timesheet and monthly pay summary

This app calculates estimated pay from the work time and hourly wage you enter. It does not automatically calculate taxes, overtime rules, holiday pay, night shift premiums or other legal payroll items, so use the result as an estimate before final payroll settlement.
