We propose abandoning fixed months in favor of a "Threshold Definition." Spring should be declared not by the calendar page turning, but when the running mean temperature crosses 10°C (50°F) for a sustained period. Under this definition, the "months of spring" are fluid, localized, and responsive to the reality of the biosphere. what months are in the spring

The question of what months are in spring cannot be answered with a single list. The paper concludes that: December solstice (around December 21)

The most common distinction is between astronomical spring and meteorological spring. Astronomically, spring is defined by the Earth’s position relative to the Sun. In the Northern Hemisphere, spring begins with the vernal equinox, which occurs around March 20 or 21, when day and night are approximately equal in length. It ends with the summer solstice around June 20 or 21, the longest day of the year. Thus, according to the astronomical calendar, spring includes the latter half of March, all of April and May, and the first part of June. In the Southern Hemisphere, the seasons are reversed: astronomical spring runs from September 22 or 23 to December 21 or 22, encompassing parts of September, all of October and November, and part of December.

The question "What months are in spring?" appears trivial, yet the answer varies wildly depending on the authority consulted. A meteorologist in London will give a different answer than a gardener in Virginia or an astronomer in Tokyo. This paper seeks to map the friction between human calendar-making and the environmental realities of the biosphere. We posit that the rigid assignment of months to seasons is a relic of administrative convenience that increasingly fails to reflect ecological reality in an era of climate change.
