- Pick a start date and an end date.
- The tool instantly counts the total days between them.
- Read the workdays (Monday to Friday), weekend days and the approximate number of weeks, including both endpoints.
Everything is calculated locally in your browser. No data is uploaded, so you can check any range freely.
Business runs on business days. A project that takes fifteen workdays is not two weeks of calendar time; a delivery promised in “ten working days” lands later than the calendar suggests; and notice periods, pay calculations and leave balances all count the same way. This calculator removes the guesswork by counting the days that actually matter, so estimates, schedules and commitments rest on a number you can trust.
Tips
Remember that both endpoints are included. A Monday-to-Friday range counts as five workdays, not four — a detail that matters for pay and leave calculations, and one this tool handles correctly by design.
Use the weekday count to set realistic deadlines. When a colleague or supplier promises “three working days”, check the calendar, add them from the start date, and confirm the actual delivery date in writing. For longer projects, multiply workdays by the team size to sanity-check effort estimates before committing to a schedule.
Why use it
Counting workdays by hand is tedious and unreliable — weekends and holidays slip in unnoticed, and every spreadsheet formula is another place to make a mistake. Calendar apps show dates but rarely count business days, and most online tools bury the feature behind ads or registration.
This calculator is instant, free and private. It gives you total days, workdays, weekends and weeks in one view, and works for any date range in any year. When the deadline matters, let the tool count the days for you.
Real-world use cases
- Home buying: Estimate monthly payment and total interest before talking to a bank. Adjust years vs. rate to see the trade-off.
- Budgeting: Use percentage and discount calculators to quickly check sale prices while shopping.
- Planning: Workday and unit converters save time when coordinating across teams and regions.
How accurate is it?
Results use standard formulas with double-precision floats, matching Excel and banking calculators to within cents. Assumptions are shown in the note (e.g., monthly compounding). For legally binding totals, confirm with the provider because fees, insurance and rounding rules differ.
Pro tips
- For loans, compare equal-payment vs equal-principal: the latter starts higher but pays less interest overall.
- For fuel and discount math, keep one decimal extra while comparing options, then round for display.
- Save results with a screenshot or copy; everything is local so refreshing clears the form.
