180 Days in Months for Different Contexts

Legal and contracts: A 180-day clause typically means 6 calendar months from the reference date, calculated month-to-month (e.g., June 1 to December 1), not a fixed 180 days. Always confirm with the contract language — “180 days” and “6 months” are legally distinct in some jurisdictions.

Visas and immigration: Schengen Area rules allow 90 days in any 180-day rolling window. The 180-day period is always measured in clock days (not months), rolling backward from the current date.

Warranties and subscriptions: A 180-day warranty period is counted in calendar days from the purchase date, not as 6 months. This matters because 6 calendar months from January 31 is July 31, which is 181 days — not 180.

How to Convert Days to Months
