Worked Examples
Example 1 - 90 days forward:
Today is October 8, 2026. Adding 90 days: 23 days left in October + 30 in November + 31 in December = 84, plus 6 days into January. Result: January 6, 2027.
Example 2 - 90 business days forward:
90 business days = 18 full work weeks = about 126 calendar days. From October 8, 2026, that lands on February 11, 2027 – useful for HR notice periods and project deadlines that skip weekends.
Example 3 - 90 days backward:
Need to know what date was 90 days ago? From October 8, 2026, counting back gives July 10, 2026 – handy for “within the last 90 days” requirements on forms and applications.
