How to use this calculator
Enter the start and end dates. Select the weekdays that count as working days, then paste any extra dates to exclude. Choose whether the start and end each count and calculate the total.
The breakdown separates non-working weekdays from extra exclusions so the same date is never removed twice. Duplicate exclusions are combined. An exclusion outside the counted range does not reduce the result. Reversed dates produce a negative working-day count; endpoint choices follow the dates as entered.
A worked example
Monday November 2 through Friday November 6, 2026 contains five Monday–Friday workdays when both dates count. Excluding November 4 leaves four. If the start date does not count, three remain.
Are public or bank holidays included automatically?
Yes, when you choose a holiday country and region. Review actual and observed dates, uncheck holidays you work, and add workplace closures. Coverage varies by region and year; manual-only calculation remains available. This tool does not determine legal deadlines.
Choose a country and region to load holidays automatically, then review the selected dates and uncheck holidays you work. Add your own closures separately. The country holiday lists explain regional coverage; public holidays do not guarantee time off for every employer.
Which calendar and years are supported?
These tools use Gregorian calendar dates for years 1–9999, without historical calendar-switch dates. They count dates, not elapsed hours. Today buttons use the current date in your browser's time zone.
What happens to my dates?
Calculations run on your device. Saving a calculation is optional and keeps it in this browser. A setup link contains the dates and settings you entered; anyone with the link can read them. Use one tab per saved calculator. Clear saved data from Privacy & settings.
Loading automatic holidays sends only the country, region and calendar years to TimeCubby. Your exact dates, times and workplace closures are not sent.
