TimecardSumHow to use this time card calculator
Start by choosing the workweek you want to check in this time card calculator. Choose Weekly or Biweekly, select your clock format, and enter each day's start and finish. You can type 9a and 5p, or use 09:00 and 17:00 in 24-hour mode. The daily result shows hours and minutes alongside decimal hours, so you can compare it with your original record.
Next, enter unpaid break minutes. Leave a day's break empty to use the default in Settings; an explicit zero means no deduction. Finally, review the total and any highlighted errors. An optional hourly rate adds a gross-pay estimate. You can add employee details before printing, but they are not required to calculate hours.
Example: a full week with lunch breaks
Suppose you work from 9:00 AM to 5:00 PM, Monday through Friday, with a 30-minute unpaid lunch each day. Each shift spans eight hours. Subtracting half an hour leaves 7:30, or 7.50 decimal hours. Five identical days total 37:30, which is 37.50 hours, not 37.30.
Enter Monday first, then use Copy weekdays to fill Tuesday through Friday. Check the copied days before using the result: a late finish or a shorter lunch changes the total. The dedicated lunch calculator also lets you record the start and end of each work period instead of entering a break duration.
| Day | In–out | Unpaid break | Work hours |
|---|---|---|---|
| Mon | 9 AM–5 PM | 30 min | 7:30 / 7.50 |
| Tue | 9 AM–5 PM | 30 min | 7:30 / 7.50 |
| Wed | 9 AM–5 PM | 30 min | 7:30 / 7.50 |
| Thu | 9 AM–5 PM | 30 min | 7:30 / 7.50 |
| Fri | 9 AM–5 PM | 30 min | 7:30 / 7.50 |
| Total | Five shifts | 150 min | 37:30 / 37.50 |
AM/PM, 24-hour time and overnight shifts
For the clearest entry, include AM or PM. When you type a bare time such as 9 or 5 in 12-hour mode, the calculator infers a meridiem and displays it beside the input. Tap that control if the inference does not match your record. Switching to 24-hour mode preserves the resolved times rather than reinterpreting the same digits.
An overnight shift belongs on the row where it began. For example, 10 PM to 6 AM spans eight hours before unpaid breaks. The overnight label is a reminder to check the dates. Equal start and finish times represent a full day, so check those carefully. This tool does not adjust durations for daylight-saving clock changes.
Weekly versus biweekly time cards
Biweekly mode gives you a second seven-day table. Enter each week in its own section, keeping the same workweek start. The calculator shows a subtotal for each week before combining the pay-period result. Under its weekly overtime setting, a 50-hour week followed by a 30-hour week has ten overtime hours, even though the two-week average is forty.
Switching back to Weekly keeps the second week's entries saved but excludes them from the visible total and exports. A notice tells you when a hidden second week contains data. Use the overtime calculator when you want the rule selector at the front of the form, especially before comparing weekly and daily calculations.
Rounding to the nearest 15 minutes
Exact minutes are the default. If you select 15-minute rounding, each clock punch moves to the nearest quarter hour before the shift duration is calculated. Around 9:00, 8:52 becomes 8:45, while 8:53 becomes 9:00. Likewise, 9:07 becomes 9:00 and 9:08 becomes 9:15. Break minutes are entered directly; the weekly total is not rounded a second time.
The chart illustrates the arithmetic, not permission to use a rounding policy. Federal guidance requires permitted rounding to avoid undercounting work over time, and state requirements can be more restrictive. California rounding questions need particular care. Keep exact minutes unless you have confirmed the applicable policy. Decimal display rounding is separate: it changes how a number looks, not the minutes used in the calculation.
| Original punch | Rounded punch |
|---|---|
| 8:52 | 8:45 |
| 8:53 | 9:00 |
| 9:07 | 9:00 |
| 9:08 | 9:15 |
Print or export your time card
Use Print time card for a clean record with daily punches, breaks, totals, and signature lines. The print layout leaves out navigation and explanatory articles. Download CSV produces an editable spreadsheet file with separate columns for the punches and hour categories. Correct any incomplete day before exporting; an error should not quietly become an apparently finished time card.
Entries save in this browser after you edit them. Refreshing restores the same tool's card, but another browser or device has its own storage. Download a copy if you need a durable record. For a quick conversion without a weekly table, open the decimal hours calculator. It also adds duration lists without rounding each line first.
