“+1d” means the shift ends after midnight. Breaks are deducted before regular and overtime totals are split.

How to use this online time card

  1. Check each day worked and enter the first clock-in and clock-out time.
  2. Enter unpaid break minutes, or enable a second daily shift when you have two separate work periods.
  3. Adjust the weekly overtime threshold if your workplace does not use 40 hours.
  4. Optionally enter an hourly rate to estimate gross regular and overtime pay.
  5. Print the completed card or export its rows and totals to CSV.

How hours worked are calculated

For each enabled day, the calculator subtracts clock-in from clock-out, adds a second work period when entered, and then deducts the unpaid break. Daily net minutes are added for the weekly total. Decimal hours equal total minutes divided by 60, so 7 hours 30 minutes becomes 7.50 hours.

Regular hours and weekly overtime

The default overtime threshold is 40 hours per week. Hours up to the threshold are regular; hours above it are overtime. When you enter a pay rate, estimated gross pay equals regular hours × hourly rate plus overtime hours × hourly rate × overtime multiplier. The tool does not calculate taxes, daily overtime, double time or employer-specific rounding.

Worked time-card examples

Standard shift with a lunch break

A 9:00 AM–5:00 PM shift is 8 hours. After a 30-minute unpaid lunch, the result is 7 hours 30 minutes, or 7.50 decimal hours.

Overnight shift

A 10:00 PM–6:00 AM shift crosses midnight and lasts 8 hours. After a 30-minute unpaid break, the result is 7 hours 30 minutes.

Weekly overtime and estimated pay

For 45 hours at $20 per hour with a 40-hour threshold and 1.5× overtime rate, the estimate is $800 regular pay plus $150 overtime pay, or $950 before taxes and deductions.

Common time-card mistakes

Enter only unpaid breaks, check AM/PM carefully, and treat an end time earlier than its start as an overnight shift. Do not assume every workplace uses the same rounding or overtime rules. Compare the result with official records before using it for payroll.
