What Is a Google Hours Calculator?
A google hours calculator is a simple way to figure out how many hours you worked between two times, minus breaks. People often search this phrase when they need a quick answer for timesheets, payroll checks, project planning, or shift scheduling.
This page gives you a fast, no-login calculator and a practical guide for using the same logic inside Google Sheets.
How This Calculator Works

Google Sheets Formulas for Hours (DIY Version)
If you want a spreadsheet workflow, these formulas are reliable:
1) Basic hours between start and end
=MOD(B2-A2,1)*24
Where A2 is start time and B2 is end time. MOD handles overnight shifts.
2) Subtract break minutes
=MOD(B2-A2,1)*24-(C2/60)
Where C2 is break minutes.
3) Weekly hours from daily hours
=D2*E2
Where D2 is net daily hours and E2 is days per week.
Common Mistakes to Avoid
- Forgetting to deduct unpaid lunch/break time
- Using end time earlier than start time without overnight logic
- Mixing decimal hours and clock format inconsistently
- Assuming every month has exactly 4 weeks
Quick Example
If you work from 8:30 AM to 5:00 PM with a 30-minute break, your daily net is 8.0 hours. At 5 days/week, that becomes 40 hours/week. Enter an hourly rate and you can estimate weekly and annual income instantly.
FAQ
Does this work for overnight shifts?
Yes. If your end time is earlier than start time, the calculator assumes your shift passes midnight.
Can I use this for part-time schedules?
Absolutely. Set the days per week and shift length to match your real schedule.
Is monthly hours exact?
Monthly hours are estimated using yearly hours divided by 12. It is great for planning, but payroll periods may vary.
Final Thoughts
A reliable google hours calculator helps you make smarter decisions about work, pay, and planning. Use the tool above for quick answers, then mirror the same logic in Google Sheets if you need ongoing tracking.
