The tool compares two calendar dates in UTC day units, then adds optional start-day inclusion, yearly-anniversary adjustment, and a business-day split for practical planning.
Some rules include the starting day and some do not. Use the include-start option to match your counting rule.
This tool excludes weekends only. Use it as a quick planning estimate, not a legal holiday calendar.
