What is WorkHoursGuide?

WorkHoursGuide is a collection of free calculators and practical guides for work hours, shifts, time cards, payroll math, breaks, PTO planning, business days, and billable time.

The site is built around everyday questions such as: How many hours did I work? What time can I clock out? How much overtime pay would these hours produce? How many business days are between two dates? How quickly will PTO accrue?

Why the site is organized into separate tools

Work-time calculations often look similar on the surface but solve different problems. WorkHoursGuide therefore keeps a clear distinction between tools such as:

  • Work Hours Calculator: start time + end time + breaks → worked time.
  • Clock Out Calculator: start time + required work + breaks → leave time.
  • Time Card Calculator: a full week of punches, breaks, overtime, and optional pay.
  • Timesheet Calculator: already-known hours allocated to projects, clients, and tasks.
  • Time Duration Calculator: pure elapsed time without payroll assumptions.

Our goals

Useful first

The calculator should answer the visitor's question quickly before asking them to read a long explanation.

Clear math

Important formulas and assumptions should be visible instead of hidden behind a result box.

No account required

The calculators are designed for direct use without requiring users to create an account.

Mobile friendly

Interfaces are designed to remain usable on desktop, tablet, and mobile screens.

What WorkHoursGuide is not

WorkHoursGuide is not a payroll provider, employer, law firm, accounting firm, tax adviser, benefits administrator, or government agency. The calculators perform arithmetic from user-supplied inputs and provide general informational explanations.

Employment, wage, overtime, meal-break, leave, tax, and PTO rules can vary significantly. Always verify the rules that apply to your specific situation before making an employment, payroll, legal, or financial decision.

How we handle accuracy

We design calculator logic around transparent formulas, test common and edge-case inputs, and provide explanatory examples so results can be checked independently. More detail is available on our Methodology page.
