In academic and business settings, seasons are often capitalized when they refer to a specific term or semester. This is common in university style guides to differentiate a general time of year from a specific enrollment period. Capitalization Rules and Examples | Grammarly
In the rigid architecture of English grammar, the rules regarding seasons are deceptively simple: spring, summer, autumn, and winter are common nouns, lowercased unless they lead a sentence or form part of a proper noun, such as the “Winter Olympics.” To “capitalize” a season, in the literal sense, is an error—a typographical mistake.

To truly capitalize a season is not merely to name it, but to invest in its unique energy, extracting maximum value from the fleeting intervals of our lives. capitalize seasons
