How to Use a Time Card

A practical method

A time card records clock-in, clock-out, and unpaid break periods for each workday. Its purpose is to preserve the original time entries and show how they become daily and weekly totals. Good records separate worked time, paid time, regular hours, and overtime instead of collapsing everything into one number.

1. Enter each work interval: Record the actual start and end time for every shift, including overnight dates when necessary.
2. Record breaks separately: Identify whether each break is paid or unpaid before deducting it.
3. Calculate daily totals: Subtract start from end, then deduct only unpaid breaks. Keep the result in minutes until the final conversion.
4. Review the weekly total: Apply the relevant regular and overtime rules only after the daily entries have been checked.

Worked example

A worker clocks in at 08:10 and out at 16:40, an elapsed span of 8 hours 30 minutes. After a 30-minute unpaid lunch, paid time is 8 hours. Repeating this for five equal days gives 40 paid hours before any jurisdiction-specific overtime rule is applied.

Checks, edge cases, and common mistakes

• Do not overwrite the original clock times after rounding the payable total.
• Make overnight shifts explicit with dates, not just an earlier end time.
• Confirm whether breaks are paid before deducting them.
• Compare the calculated total with the applicable workplace policy and local law.
