What Is 180 Calendar Days From Today?
180 calendar days from today is —. "Calendar days" means every day of the week — weekends and public holidays are all counted. This distinction matters when contracts, statutes, or deadlines specifically say "calendar days" instead of "business days".
One hundred eighty calendar days is the federal EEOC statute of limitations window, extending to 300 days in states with their own fair employment agencies.
Calendar Days vs. Business Days
This is the difference that trips people up most. Calendar days count every single day — Monday through Sunday, plus holidays. Business days only count Monday through Friday, skipping weekends (and sometimes federal holidays, depending on context).
Specific uses: One hundred eighty calendar days is the EEOC discrimination claim filing window (extended to 300 days in deferral states), the IRS six-month tax extension deadline, and the typical 'statute of limitations' window for many consumer protection claims under state UDAP laws.
When To Use Calendar Days
Calendar-day counts are the default in most US legal and commercial contexts. You'll see them explicitly required in:
- Tax filings and IRS extension windows
- Real estate closing deadlines (including 1031 exchanges)
- Federal and state statutes of limitations
- Product return and warranty policies
- Insurance claim filing windows
Under Title VII of the Civil Rights Act, a charge must be filed with the EEOC within 180 calendar days of the alleged discriminatory act. That window extends to 300 days in 'deferral states' that have their own equivalent agency. When in doubt, file earlier.
