What 180 Days Actually Means
six months — exactly half a year
One hundred and eighty days is exactly half a year and comes up everywhere in long-dated planning. It's the second half of the IRS 1031 exchange timeline (45 days to identify, 180 days to close). It's the second half of the Schengen 90/180 rule. Most passports must be valid at least 180 days past your planned entry date to let you board an international flight — a rule that catches millions of travellers every year.
In finance, 180 days is the most common term for short-term commercial paper and certain central-bank liquidity operations. In contract law, it's a common limitation period for filing employment discrimination complaints with the EEOC (though this varies by state). In medicine, 180 days is the window most transplant programs use to evaluate graft survival.
Common Uses for a 180-Day Window
- Passport six-months-validity requirement for most international travel
- IRS 1031 exchange closing deadline
- EEOC filing window for discrimination complaints (180 or 300 days)
- Short-term commercial paper and money-market instrument maturity
- Schengen rolling-window denominator (90 days allowed per 180)
Did you know?
The "six-months-passport-validity" rule isn't international law — it's a patchwork of individual country requirements. But because airlines are fined by destination countries when they board a passenger who gets refused entry, airlines enforce it proactively, making it effectively universal.
How This Calculation Works
This page counts exactly 180 calendar days forward from today — weekends and holidays included. The calendar below marks every day in the range, so you can trace the span visually and double-check against a month boundary or holiday. If you need to count only working days instead, use the business days calculator. For "N days ago" calculations, use the main days calculator and switch to Subtract mode.
