Reconstructing two weeks by hand? Let InstaClock keep the running total

Plenty of employers run a two-week pay period, so a single weekly time card means adding two of them together. Fill in your clock-in and clock-out times (and each day’s break) across both weeks and this calculator gives you a subtotal for week one, a subtotal for week two, and the combined biweekly total — in hours and minutes and in the decimal hours payroll uses. Leave any day blank and it counts as a day off.

The method

How this calculation works

  1. 01For each day, convert clock-in and clock-out into minutes and subtract that day’s unpaid break.
  2. 02Add the seven daily totals in each week to get that week’s subtotal.
  3. 03Add the two weekly subtotals together for the biweekly pay-period total.
  4. 04Divide the total minutes by 60 for decimal hours.
  • Each week is subtotalled separately, which mirrors how biweekly pay stubs usually break the period down.
  • Any day left without a clock-in or clock-out is treated as a day off (zero hours).
  • Breaks are per-day and unpaid — set a day’s break to 0 if it was paid.
  • Overnight shifts are handled per day, and the two-week total is a plain sum with no overtime multiplier applied.

Worked examples

Two identical Mon–Fri weeks, 09:00–17:00 with a 60-min lunch

35h 00m + 35h 00m = 70h 00m (70.00 decimal hours)

Week 1 four 10-hour days; Week 2 five 8-hour days, 30-min breaks

38h 00m + 37h 30m = 75h 30m (75.50 decimal hours)

Week 1 full-time; Week 2 three days off

40h 00m + 16h 00m = 56h 00m (56.00 decimal hours)

Frequently asked questions

How do I calculate a biweekly time card?
Total each week the usual way — subtract clock-in from clock-out and take off breaks for each day, then add the days — and finally add the two weekly totals together. This calculator shows both weekly subtotals and the combined two-week total automatically.
What is the difference between a weekly and biweekly time card?
A weekly time card covers seven days; a biweekly one covers a full 14-day pay period. Biweekly is common because many employers pay every two weeks, so this calculator keeps each week’s subtotal visible while giving you the combined figure to submit.
Does it handle overtime across the two weeks?
It sums the exact hours worked without applying an overtime multiplier, since overtime rules vary by region and are often calculated per week. Use the per-week subtotals as the basis for any overtime your rules require.
Is there an easier way than filling this in every pay period?
Yes — InstaClock records your hours as you work and keeps the running weekly and pay-period totals, so at the end of two weeks the number is already there instead of reconstructed from memory.
