About the tools
About Shift Ledger
Free work-hours calculators and timecard tools for U.S. hourly workers. Why these tools exist and who maintains them.
A practical companion to your timecard
Shift Ledger helps U.S. hourly workers check their own work hours, finish a paid-hours target, and prepare a readable timecard. Its focus is arithmetic you can inspect, not payroll administration.
There are 22 calculators covering 22 related tasks. No account is required. The site has no server database for schedules and does not submit payroll or contact employers.
Why these tools exist
Most workers need to check their hours at some point. Maybe your paycheck does not match what you expected. Maybe you are switching from a 5/8 to a 4/10 schedule and want to see the pay difference. Maybe you need to fill out a timecard and want to make sure the math is right before you submit it.
Shift Ledger gives you a way to do that arithmetic yourself. Every calculation is visible. You enter the numbers, press Calculate, and see the breakdown. There is no hidden formula and no server processing your data.
How the tools work
All calculators run in your browser using JavaScript. Clock times are converted to whole minutes. Unpaid breaks are subtracted from total time on site. The result is displayed as hours and minutes, decimal hours, or both. Gross pay is calculated as minutes divided by 60 times the hourly rate, rounded to cents.
The calculation methodology page explains every formula in detail. Automated tests verify standard shifts, overnight periods, timecard boundaries, and edge cases. No professional payroll certification or expert review is claimed.

The tools are built to be simple, fast, and private. Every calculation runs in your browser. No data is sent to a server. No accounts are required. The goal is to give U.S. hourly workers and freelancers a straightforward way to check their own hours, pay, and PTO without relying on opaque payroll software.
Pay and leave tools use the assumptions you enter. No professional payroll certification or expert review is claimed. State and federal tax estimates use published brackets and are clearly labeled by year. Formulas and edge cases are documented in the calculation methodology.
