There is a third, arguably more romantic definition of spring that doesn't look at a clock, calendar, or telescope. This is —the season defined by the behavior of living things.
Meteorologists often define seasons in three-month blocks to simplify climate data. In this system, spring consists of the three months with the fastest increasing temperatures: March, April, and May in the Northern Hemisphere, and September, October, and November in the Southern Hemisphere.
Spring is defined as the temperate season occurring between and summer . It is characterized by rising temperatures, lengthening daylight, and the "awakening" of nature. spring definition season

Used by weather forecasters for consistent record-keeping, dividing the year into three-month blocks based on temperature cycles. Northern Hemisphere: March, April, and May. Southern Hemisphere: September, October, and November. Ecological/Phenological: There is a third, arguably more romantic definition
Phenology is the study of periodic biological phenomena, such as flowering, breeding, and migration, in relation to climate. The phenological definition of spring is completely fluid and relies entirely on indicators from nature rather than dates on a calendar.
Astronomically, spring is defined by the positioning of the Earth relative to the sun. It begins with the vernal equinox and ends with the summer solstice. The Vernal Equinox In this system, spring consists of the three
The swelling of tree buds, the emergence of early wildflowers (like snowdrops and crocuses), and the leafing out of deciduous trees.
In the Northern Hemisphere, meteorological spring spans exactly three months: March, April, and May.
As the ground thaws, trees begin drawing water and nutrients up from their roots.
