This is a manual-entry time card calculator, not a connected employee time clock. Your records are stored locally where browser storage is available. Back them up before switching devices.
Complete your time card in three steps.
Start with the pay period, record clock punches for each worked day, then review missing entries and confirm the reported total.
Choose your pay period
Select seven or fourteen days, choose a starting date, and optionally add an employee name or time-card reference.
Enter daily punches
Record clock-in, lunch-out, lunch-in and clock-out. Add extra punch pairs for split work or a second session.
Reconcile the results
Review each day's total, inspect incomplete punches or overlapping intervals, and save or export your card.
A time card is more than a start and finish time.
A proper time card can contain a morning clock-in, a lunch clock-out, a return-from-lunch clock-in, and a final clock-out. Some days also include additional punch pairs.
ScheduleFlowLab preserves these separate entries. It does not assume that time away between lunch punches counts as work. Optional additional unpaid break minutes are deducted separately.
Understand time-card punches, breaks and pay-period totals.
Learn how time-card reconciliation works, how to handle lunch-out and lunch-in punches, what happens with a missing clock-out, when rounding changes a recorded duration, and how to review a weekly or biweekly card.
What is a time card calculator?
A time card calculator converts recorded attendance punches into daily and pay-period time totals. Instead of entering a single number of hours worked, you provide the clock readings recorded when work starts, stops and resumes.
A typical time card includes an employee's name, a pay-period starting date, a clock-in time, a clock-out time, and any breaks taken during the day. A more detailed punch card records a lunch-out and lunch-in time separately.
These entries are reconciled by pairing each clock-in with the corresponding clock-out. The duration of every completed working interval is calculated, then those intervals are added.
ScheduleFlowLab uses exact minutes by default. Every completed day contributes to its seven- or fourteen-day time-card total. Days with missing or invalid punches are flagged rather than assigned guessed times.
Because a manually entered time card cannot independently verify attendance, all figures should be checked against the relevant records before they are used for payroll or other formal purposes.
How lunch-out and lunch-in punches are calculated
A four-punch workday normally records the beginning of work, the beginning of an unpaid lunch, the return from lunch and the end of work.
For example, clocking in at 9:00 AM, going to lunch at 12:30 PM, returning at 1:00 PM and clocking out at 5:30 PM gives two working intervals.
The first interval lasts three hours and thirty minutes. The second lasts four hours and thirty minutes. Their combined duration is eight hours.
The thirty-minute gap between lunch out and lunch in has already been excluded. Do not enter that same thirty minutes again in the additional break field, or the lunch period will be deducted twice.
If the time card records only the first clock-in and final clock-out, you can leave both lunch punch fields blank and enter any unpaid meal deduction in the separate break-minutes field.
What to do when a time card has missing punches
Missing clock punches are a common time-card problem. An employee may forget to clock out before lunch, clock back in afterward or record the final finish time.
A calculator should not silently turn an incomplete punch sequence into an invented worked-hours figure. Missing boundaries make the underlying interval uncertain.
This calculator displays a warning when a required punch is missing, when only one lunch punch has been entered, or when a punch sequence is chronologically impossible.
An invalid day is excluded from the calculated numeric total until the missing information is corrected. The remaining valid days can still be inspected, but the pay-period result is marked provisional.
Compare any flagged entry with the employee's actual attendance record, authorized correction or other reliable source. A mathematically inferred time should not be represented as a verified clock punch.
Reconcile seven-day and fourteen-day time cards
Weekly time cards contain seven consecutive dates. Biweekly time cards contain fourteen consecutive dates. Each day can contain one or more completed work intervals.
A seven-day card might contain five eight-hour workdays, producing forty credited hours. A fourteen-day card may contain two such weeks, producing eighty credited hours.
The calculator keeps separate first-week and second-week totals within the selected fourteen-day period. It then adds both to obtain the pay-period total.
This separation is helpful when verifying that the records belong to the correct pay period or identifying which week contains an incomplete entry.
A pay-period total does not automatically classify overtime. The meaning of an employer's workweek, overtime eligibility and any applicable thresholds must be evaluated separately.
Overnight punch records are attributed to their starting time-card date for display in this tool. They are not automatically divided at midnight.
How to reconcile more than four punches in one day
Not every working day follows a standard four-punch pattern. Some employees work an additional evening session, return for an emergency call, or have other separate periods of recorded work.
The time-card table includes a details control for each day. Open it to add extra clock-in and clock-out pairs beyond the primary workday punches.
Each additional pair is calculated as its own interval. The intervals are then added into the day's credited total, subject to any additional unpaid break-minute deduction.
For instance, a person working 8:00 AM to noon and again from 4:00 PM to 7:00 PM records seven hours across two separate intervals.
When two recorded working intervals overlap, their shared minutes could be counted twice. The calculator flags these overlaps and marks the result provisional instead of silently deciding which punch should be changed.
Understand optional time-clock rounding
Some organizations record clock punches to the nearest time increment rather than using every exact minute.
For example, with nearest fifteen-minute rounding, a clock-in recorded at 8:53 AM becomes 9:00 AM for the calculation. A clock-out at 5:07 PM becomes 5:00 PM under the same rule.
This calculator can simulate nearest five-minute, six-minute or fifteen-minute rounding. Each recorded punch is adjusted individually before its corresponding interval is calculated.
The exact original result and the rounded result are kept separate so any difference can be reviewed. Additional unpaid break minutes remain exact.
Rounding can increase or decrease a particular day's apparent worked time. A mathematical rounding option is not proof that a rounding practice is permitted in any jurisdiction.
For example, US federal rules under 29 CFR §785.48 address accepted rounding practices under conditions concerning proper compensation over time. Employers should review the applicable law and the effect of any chosen policy.
Record a clock-out that occurs the following day
Overnight time cards require correct date handling. A worker may clock in at 10:00 PM and finish at 6:00 AM the following morning.
Those punches describe an eight-hour interval under ordinary wall-clock arithmetic, not a negative duration.
Open the relevant day's details and enable the next-day clock-out setting. The calculator then handles the date rollover while preserving the workday on which the period began.
This page does not automatically adjust durations for daylight-saving transitions. A work interval crossing a clock change may require a separate actual-elapsed-time calculation.
When an overnight interval conflicts with a second recorded session, an overlap warning appears. This helps identify accidental double counting across adjacent dates.
Convert the reconciled time card into decimal hours
Time cards often display hours and minutes alongside decimal hours. These formats describe the same duration, but minutes are not hundredths of an hour.
For example, forty-two hours and thirty minutes is equivalent to 42.50 decimal hours. Forty-two hours and forty-five minutes is equivalent to 42.75 decimal hours.
This calculator adds whole-minute durations before dividing the final value by sixty.
This avoids relying on separately rounded decimal values from each workday, which can cause small differences when totals are added.
Two, three or four decimal places may be used for display. The displayed precision does not change the time-card's underlying calculated minutes.
Review your time card before using the total
An accurate time-card calculation requires complete punches, correctly interpreted breaks and a clearly defined pay period.
Check that every required clock-in has a matching clock-out. Make sure the lunch fields are either both completed or both intentionally blank.
Review whether additional unpaid breaks have already been excluded through separate out-and-in punches. Entering the same break twice would incorrectly reduce the total.
Inspect overlap warnings, especially on days containing extra punch pairs or overnight work.
If rounding is enabled, compare the exact and adjusted time-card totals. Record which calculation method was used when exporting a report.
Finally, verify the employee identity and pay-period dates. This calculator produces a calculation from entered records; it does not independently establish that those records are complete, approved or legally compliant.

What is a time card calculator?
It adds the durations between recorded clock-in and clock-out punches, accounts for excluded breaks, and produces daily and pay-period totals.
How do I calculate a time card with lunch?
Enter the initial clock-in, lunch-out, lunch-in and final clock-out. The time between lunch out and lunch in is already excluded.
Can I leave the lunch fields blank?
Yes. Leave both lunch fields blank to calculate a continuous in/out interval. You can enter any separately recorded unpaid deduction in Break min.
What happens if only one lunch punch is entered?
The day is marked incomplete and excluded from the numeric total until the missing lunch punch is supplied or both lunch fields are cleared.
Can I calculate a biweekly time card?
Yes. Select Biweekly to display fourteen consecutive dates, separate weekly totals and one combined pay-period total.
Can one day contain multiple in/out pairs?
Yes. Expand the day details to enter additional punch pairs for split shifts, second sessions or extra recorded working intervals.
Does it calculate overnight punches?
Yes. Enable the appropriate next-day option when a clock-out occurs after midnight. The tool uses wall-clock arithmetic.
How does punch rounding work?
The advanced option can round individual punches to the nearest five, six or fifteen minutes before calculating intervals. Exact minutes remain the default.
Does rounding automatically follow labor laws?
No. The tool simulates mathematical rounding only. The legality of any rounding method depends on the relevant rules and how it is applied.
Can I see the difference caused by rounding?
Yes. The review panel shows exact recorded time, the rounding adjustment and the final reported result.
What if two recorded working intervals overlap?
An overlap warning identifies the conflicting intervals. The reported total is marked provisional until you review the records.
Does this time card calculate overtime wages?
No. The page reconciles time punches and totals. Overtime classification and pay estimates belong to the separate Overtime Calculator.
How are decimal time-card hours calculated?
Total credited minutes are divided by sixty. For example, forty-two hours and thirty minutes equals 42.50 decimal hours.
Can I export the time-card punches?
Yes. You can export a CSV file, print a time-card report or download a JSON backup containing saved data and scenarios.
Can I import an existing time card?
CSV import accepts the format exported by this calculator. JSON restoration can recover a previously saved calculator backup.
Is this a real employee time clock?
No. The calculator processes manually entered punches. It does not independently timestamp attendance, authenticate employees or submit records to payroll software.
Calculate and review your employee time card.
Record each punch, inspect incomplete entries, and export a clear weekly or biweekly calculation.
