How to Use the Time Card Calculator
Overview
This calculator helps you track work hours for each day of the week and automatically calculates total hours, overtime, and break deductions. Perfect for employees, contractors, and employers who need accurate time tracking.
How Time Card Hours Are Calculated
Daily Hours: End time minus start time, minus any break time
Regular Hours: Total weekly hours up to the overtime threshold (default: 40 hours)
Overtime Hours: Any hours worked beyond the regular hour limit
Break Deduction: Automatically subtracted from daily totals when enabled
How Input Rounding Works
Rounding helps standardize time entries for payroll purposes:
5-Minute Rounding:
9:07 → 9:05 | 9:13 → 9:15 | 9:18 → 9:20
6-Minute Rounding (1/10 hour):
9:03 → 9:00 | 9:09 → 9:06 | 9:15 → 9:18
15-Minute Rounding:
9:07 → 9:00 | 9:23 → 9:30 | 9:38 → 9:45
Note: Rounding applies when you finish entering a time and move to the next field. Times are rounded to the nearest interval using standard rounding rules.
Step-by-Step Guide
1. Enter Times

2. Add Breaks
Enter break duration in minutes (e.g., "30" for 30 minutes, "60" for 1 hour)
3. Set AM/PM
In 12-hour mode, click AM/PM buttons to set the correct time period
4. Review Results
Check the summary table for total regular hours, overtime, and weekly totals

Round Inputs
Automatically round time entries to nearest 5, 6, or 15-minute intervals. For example: with 15-min rounding, 9:07 becomes 9:15, and 9:23 becomes 9:30. 6-minute rounding is commonly used for payroll (1/10th hour increments).
