What is calculated
Total dated and overnight shifts after entered unpaid breaks, keep workweeks separate, show decimal hours, and optionally estimate simple regular and overtime pay.
Weekly Time Card and Break Calculator
Enter your plan and calculate to see the result and its assumptions.
Method
Each valid shift is measured in the selected wall-clock or elapsed-time mode, entered unpaid breaks are deducted, and counted minutes are allocated to the chosen workweek before pay is estimated.
Important boundary
The pay output is a planning estimate, not a payroll record or legal overtime decision. Daily overtime, multiple rates, bonuses, withholding and employer rounding rules are outside this model.

Result + assumptionsInterpretation
Counted hours include only the shifts and break treatment entered; paid breaks remain in time and explicitly unpaid breaks are deducted.
Each selected workweek is totaled separately, so overtime is never created by averaging hours across two weeks.
The optional pay estimate uses the entered hourly rate, weekly threshold and multiplier; confirm actual payroll rules and rates independently.

Recorded method
No tool-specific review method has been recorded.
These records describe the published model and reference tests. A test-case count is not a certification of every possible input or an independent specialist review. Editorial policy
Known limitations
- The pay result is a simple estimate, not statutory payroll or wage advice.
- Wall-clock hours and elapsed hours can differ at daylight-saving transitions; choose a named IANA zone for elapsed mode.
- Multiple rates, bonuses, daily overtime, withholding, exemptions and employer rounding rules are outside this version.

How the time card totals a shift
Enter both calendar dates and clock times. The calculator subtracts valid, user-designated unpaid break intervals from each gross shift interval; paid breaks remain in counted time. Quick break minutes are available when an entire shift stays in one workweek. For a shift that crosses a workweek boundary, use dated break intervals so each side receives the correct deduction. Overlapping shifts or breaks are flagged before totaling.
Counted minutes are summed separately for every selected workweek, then divided by 60 to show exact-derived decimal hours. An optional simple pay estimate applies your hourly rate, chosen weekly threshold and multiplier separately to each workweek. It does not average two weeks or use rounded display hours as the pay input.
Overnight and spreadsheet example
A shift from 22:00 on October 2 to 06:00 on October 3 is eight gross hours. With a 30-minute unpaid break it counts as 7 hours 30 minutes, or 7.5 decimal hours. Five such 7.5-hour shifts total 37 hours 30 minutes. For a 45-hour week at 20 per hour, threshold 40 and multiplier 1.5, the simple gross estimate is 40 × 20 + 5 × 20 × 1.5 = 950.
For full spreadsheet date-time values, gross decimal hours are (end-start)*24; subtract entered unpaid break minutes divided by 60. A MOD(end-start,1) shortcut can lose whole days. A spreadsheet alone also does not resolve ambiguous or nonexistent local times when clocks change.
Wall clock or actual elapsed time?
Wall-clock mode treats entered local dates and times as ordinary arithmetic. Elapsed mode resolves actual instants in the named IANA time zone: a New York 01:30–03:30 shift on March 8, 2026 spans 120 wall-clock minutes but 60 elapsed minutes. A repeated local time on November 1, 2026 requires an explicit earlier or later choice. This tool does not infer a time zone from abbreviations such as CST or from your device.
Workweek boundaries are the selected dated start and time. In elapsed mode, choose local-calendar boundaries or a fixed 168-hour span anchored at the selected first start instant. Legal workweek, break and overtime rules vary; the tool reports the convention used rather than deciding legal entitlement.
Overnight shifts and unpaid breaks
For a shift crossing midnight, enter both calendar dates and place each unpaid break on the date it actually occurs. If the shift also crosses a workweek boundary, dated break intervals keep the deduction in the correct week. The overnight shifts and breaks guide walks through that timeline before the pay estimate is applied.
Common time-card questions
Does a paid lunch reduce hours?
No. Only breaks you explicitly mark unpaid reduce counted minutes; check your applicable rules and employer policy separately.
Can I enter two shifts in one day?
Yes. Add another dated row. Adjacent shifts are allowed, but overlapping shifts are rejected.
Already know the weekly total?
