About Hitchday
Hitchday is a free calendar and pay estimator for people who work rotating shifts: 14 on/14 off hitches, 7/7, 4/4, DuPont, Pitman and crews that switch between day and night blocks. It is a small independent project, built because ordinary calendars and pay calculators assume a Monday-to-Friday job.
What it does
- Calendar. Set up your rotation once and see every shift for months or years ahead, mark days off, add extra shifts, and share or print your schedule.
- Gross pay. Overtime is worked out per fixed workweek, the way federal law counts it, and then placed on the paycheck it belongs to, so a workweek split by a pay period is handled correctly. Night differentials and holiday premiums are included if you have them.
- Take-home estimate (optional). Federal withholding from your W-4 answers, Social Security, Medicare, an estimate of state income tax for every state, and the deductions you enter.
How the estimates are checked
The pay calculations are compared against a separate implementation written in another programming language, on randomized schedules that include clock changes and overnight shifts. The state tax estimates are checked the same way, for every state, filing status and pay frequency. Hundreds of automated tests use answers worked out by hand. The rules and their limits are written down on the assumptions page.
Checks like these show the calculator does what it says. They cannot show that your employer, union contract or state follows the same rules, so your pay stub and your employer's payroll records always decide.
Your data stays on your device
There are no accounts. Your rotation, pay rate and tax settings are saved in your own browser and never sent to Hitchday. The site works offline after your first visit. Details are in the privacy policy.
Free to use
Hitchday is free. To cover running costs, guide pages may show clearly labeled advertising in the future; if that happens, the privacy policy will be updated first to say which provider is used and how to opt out.
