1. What is Daily Hours Calculation?

The daily hours calculation determines the actual time spent working by subtracting lunch breaks and other non-working periods from the total time between start and end of the workday.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• End Time — When the workday ends (24-hour format)
• Start Time — When the workday begins (24-hour format)
• Lunch Break — Duration of unpaid break in hours

Explanation: The calculator converts the start and end times to decimal hours, subtracts the lunch break duration, and returns the net working hours.

3. Importance of Tracking Work Hours

Details: Accurate work hour tracking is essential for payroll calculation, productivity analysis, labor law compliance, and personal time management.

4. Using the Calculator

Tips: Enter start and end times in 24-hour format (HH:MM). Input lunch break duration in hours (e.g., 0.5 for 30 minutes). All values must be valid.

5. Frequently Asked Questions (FAQ)

Q1: Should I include overtime in this calculation?
A: This calculator shows regular working hours. Overtime should be calculated separately based on your organization's policies.

Q2: How do I account for multiple breaks?
A: Sum all unpaid break durations and enter the total in the lunch break field.

Q3: What if I work overnight shifts?
A: For overnight shifts, you'll need to add 24 hours to the end time (e.g., 09:00 to 02:00 becomes 09:00 to 26:00).

Q4: How precise should my time entries be?
A: Round to the nearest quarter hour (0.25 hours) for most practical purposes, unless exact minute tracking is required.

Q5: Can this be used for weekly hour calculations?
A: This calculates daily hours. For weekly totals, sum the daily hours across your workweek.
