Frequently Asked Questions
What is a time card calculator?
A time card calculator is a tool that helps you calculate your total worked hours across multiple days. You enter your clock-in and clock-out times for each day, subtract any breaks, and the calculator gives you daily and weekly totals in both hours/minutes and decimal format for timesheets.
How do I calculate my weekly hours?
To calculate weekly hours: 1) Enter your clock-in and clock-out times for each day you worked. 2) Enter any break time taken each day. 3) The calculator automatically computes each day's hours and sums them for a weekly total. For a standard 9-5 job with 30-minute lunch breaks, you'd work about 37.5 hours per week.
What are decimal hours and why do I need them?
Decimal hours express time as a decimal instead of hours and minutes. For example, 7 hours 30 minutes = 7.50 decimal hours. Many payroll systems and timesheets require decimal hours because they're easier to multiply by hourly rates. To convert: divide minutes by 60 and add to hours.
How do I handle overnight shifts?
The calculator automatically detects overnight shifts. If your clock-out time is earlier than your clock-in time (e.g., 10 PM to 6 AM), it calculates the time correctly across midnight. You'll see a moon icon indicating an overnight shift.
Should I include lunch breaks in my time card?
It depends on your employer's policy. Paid breaks should be included in your hours. Unpaid breaks (typically lunch) should be deducted. This calculator lets you specify break time for each day, which is subtracted from your gross hours to give you net hours worked.
What's the difference between weekly and biweekly?
Weekly tracks a single 7-day period (typically Monday-Sunday). Biweekly tracks two consecutive weeks (14 days total). Many companies pay biweekly, so having a 2-week view helps you track hours for your entire pay period.
