Why month counts disagree with each other

A month is the one unit on the calendar with no fixed length. Calendar counting gives 2. Dividing 89 days by the average month of 30.436875 days gives 2.92, and dividing by a flat 30 gives 2.97. All three are defensible, and they differ because February runs to 28 days while December runs to 31. The headline figure here is the calendar one, because that is what people mean when they say they have 2 months to get ready.

The months between now and Winter Solstice
