How many months until Patriot Day?
11 months and 19 days. The count steps the month number forward from September 23, 2026 while keeping the day of the month fixed, which is what a calendar month actually is. After 11 steps the date reaches August 23, 2027, and 19 further days are needed to land on September 11. Held on 11 September in remembrance of the 2001 attacks. A national day of observance rather than a public holiday.
Why month counts disagree with each other
A month is the one unit on the calendar with no fixed length. Calendar counting gives 11. Dividing 353 days by the average month of 30.436875 days gives 11.60, and dividing by a flat 30 gives 11.77. All three are defensible, and they differ because February runs to 28 days while September runs to 30. The headline figure here is the calendar one, because that is what people mean when they say they have 11 months to get ready.
