Working Days Calculator

The tool separates total days, working days, and weekend days for a chosen date range.

You can switch the weekend model between Saturday+Sunday and Sunday-only.

Public holidays and company-specific calendars are not included in this version.

Use the result as a base estimate, then layer local holiday rules if needed.

The difference between the start and end date changes depending on whether the end date is included.

For delivery dates, contract periods, or team plans, use the same inclusion rule consistently across records.

Some teams treat Saturday and Sunday as the weekend, while some operations only exclude Sunday.

The tool lets you choose the model, but it does not verify local labor rules or company policy.

Working-day counts can be a starting metric for sprint planning, proposal delivery, SLA estimates, or staffing capacity.

The result is not an official deadline or legal time calculation; critical work should include holiday calendars and expert review.

Recheck the result whenever the date range, inclusion rule, or weekend model changes.

Company leave days, regional holidays, and half-day rules should be layered separately on top of the base value.
