From: | To: |
Definition: This calculator computes the actual working hours in a day by subtracting break time from the total time between start and end times.
Purpose: It helps employees, freelancers, and employers accurately track working hours for payroll, productivity analysis, and time management.
The calculator uses the formula:
Where:
Explanation: The difference between end and start times gives gross hours, then break time is subtracted to get net working hours.
Details: Proper work hour tracking ensures fair compensation, compliance with labor laws, and accurate project time estimation.
Tips: Enter all times in hours (e.g., 8.5 for 8 hours 30 minutes). Break time defaults to 0 if none taken.
Q1: How do I enter times like 9:30 AM?
A: Convert to decimal hours (9:30 AM = 9.5 hours). 30 minutes = 0.5 hours, 15 minutes = 0.25 hours.
Q2: What if my end time is the next day?
A: Add 24 hours to the end time (e.g., start at 20:00, end at 4:00 next day = 28.00 - 20.00).
Q3: Should I include unpaid lunch breaks?
A: Yes, include all breaks where you're not working, whether paid or unpaid.
Q4: Can I use this for multiple shifts?
A: Calculate each shift separately then sum the results for total daily hours.
Q5: What if my result is negative?
A: The calculator automatically shows 0 if breaks exceed work duration.
