Biweekly Time Card Calculator
Total a full 14-day pay period at once. Overtime is figured the right way — per week, not on the two-week sum — and breaks, rounding, and pay all carry through both weeks.

- Fill in clock-in and clock-out for each day across Week 1 and Week 2. Blank days count as zero, so it is fine to skip days off.
- Set a default lunch break and press "Apply to all days", or add per-day breaks with "+ break".
- Switch on overtime and confirm the weekly threshold (40 hours by default). Each week is judged on its own.
- Add your hourly rate to see regular pay, overtime pay at 1.5×, and the two-week gross.
- Print the timesheet or export CSV for payroll. No account, ever.
Why biweekly overtime is calculated per week
The most common mistake with a two-week card is adding all 14 days together and comparing the total to 80 hours. That is not how overtime works in the United States. The Fair Labor Standards Act defines overtime by the workweek, a fixed and recurring period of seven consecutive days. Each week stands alone.
Here is the practical difference. Suppose you work 45 hours in Week 1 and 35 hours in Week 2. The two-week total is 80 hours, which looks like no overtime. But because Week 1 crossed 40, those 5 hours are overtime and must be paid at 1.5×, even though the second week was light. ShiftTally buckets your days into two seven-day weeks, checks each against the threshold, and adds up the overtime week by week — so the number matches what a compliant payroll system produces.
What each column does
The Breaks column holds unpaid minutes and is subtracted from that day's gross shift. The Hours column shows the finished daily figure in both hh:mm and decimal. The result panel at the bottom gives the period total, then splits it into Regular and Overtime once overtime is enabled.
Rounding still applies
If your employer rounds punches, choose 5-, 6-, or 15-minute rounding. The 15-minute option is the 7-minute rule, where a punch in the first seven minutes of a quarter-hour rounds down and the last seven round up. Rounding is applied to every punch across both weeks before the daily and weekly totals are formed.
Prefer a single week or a full month?
Use the weekly time card calculator for one week, or the monthly and semi-monthly calculator when your employer pays on the 1st and 15th or once a month.
Frequently asked questions
How is overtime calculated on a biweekly time card?
Overtime is calculated per workweek, not per two-week period. ShiftTally totals each 7-day week separately, applies your weekly threshold, and only counts hours above it as overtime. So 45 hours one week and 35 the next gives 5 overtime hours, not zero.
How many days are on a biweekly time card?
Fourteen. A biweekly pay period covers two consecutive workweeks, which is 14 days. The calculator shows both weeks and keeps a running total for the whole period.
Can I leave days blank if I did not work them?
Yes. Any day with no clock-in and no clock-out is skipped and counts as zero. Only days with times entered add to the total.
Does it handle overnight shifts across the two weeks?
Yes. On any day, if the clock-out is earlier than the clock-in, the shift is treated as crossing midnight and 24 hours are added automatically.
Will my entries still be here when I come back?
Yes, on the same browser and device. Entries are stored in local storage, so a refresh or return visit keeps the card. Use "Clear all" to wipe it.
