Why You Should Use This Tool

Track Business and Legal Deadlines

Many documents include terms like “90 days’ notice” and “60 day deadline”. Using this utility will give you accurate dates in seconds.

Business Days Option

In case your business needs to count days while excluding weekends, simply use the “Business Days” mode. This can come handy for HR managers, accountants, and project managers.

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.
