How many months until Tax Day?
6 months and 23 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 6 steps the date reaches March 23, 2027, and 23 further days are needed to land on April 15. The usual US federal income tax filing deadline, 15 April. It shifts to the next working day when it falls at a weekend or on a holiday, so confirm the exact date with the IRS each year.
Why month counts disagree with each other
A month is the one unit on the calendar with no fixed length. Calendar counting gives 6. Dividing 204 days by the average month of 30.436875 days gives 6.70, and dividing by a flat 30 gives 6.80. All three are defensible, and they differ because February runs to 28 days while April runs to 30. The headline figure here is the calendar one, because that is what people mean when they say they have 6 months to get ready.
