How many months until Spring Equinox?
5 months and 24 days. The count steps the month number forward from September 24, 2026 while keeping the day of the month fixed, which is what a calendar month actually is. After 5 steps the date reaches February 24, 2027, and 24 further days are needed to land on March 20. The March equinox, when day and night are close to equal length and astronomical spring begins in the northern hemisphere. The exact moment moves between 19 and 21 March.
Why month counts disagree with each other
A month is the one unit on the calendar with no fixed length. Calendar counting gives 5. Dividing 177 days by the average month of 30.436875 days gives 5.82, and dividing by a flat 30 gives 5.90. All three are defensible, and they differ because February runs to 28 days while March runs to 31. The headline figure here is the calendar one, because that is what people mean when they say they have 5 months to get ready.
