When this tool is useful
Estimate available workdays for a delivery schedule, leave request or internal plan. Choose a weekend pattern and paste the holiday dates that apply to your organization. The result separates working days, excluded weekend days and excluded weekday holidays, so a holiday that falls on a weekend is not subtracted twice. The example uses a custom holiday solely to demonstrate the input format.
Reading the result and limitations
The start date is included, while end-date inclusion is an explicit option. Holiday calendars are not downloaded or inferred from a country, and this is not a payroll or legal deadline service. Enter dates in YYYY-MM-DD form; duplicates in the holiday list count once. Reversed ranges and intervals longer than 36,600 days are rejected. Check local rules and any partial working days before using a count in an operational schedule.
