Read the passage and answer the question.

Harvest festivals, found in agricultural societies across the world, historically marked the culmination of a farming year's labour and served practical as well as celebratory purposes. Beyond feasting, these gatherings often functioned as informal marketplaces where surplus grain, tools, and livestock changed hands before winter set in, and as occasions for settling debts accumulated during the growing season. Anthropologists studying such festivals note that their timing was rarely arbitrary: communities scheduled celebrations around the completion of specific crops rather than fixed calendar dates, meaning the exact date could shift by weeks depending on that year's weather. This flexibility distinguishes harvest festivals from religious holidays fixed to an unchanging calendar, and it reflects the festivals' origins in agricultural necessity rather than doctrinal observance.
