Why is the ninth month called September?
c.1400, "piece of reed or hollow stem of a feather," probably related to Middle High German kil "quill," from Low German quiele, of unknown origin. Meaning "pen made from a (goose) quill" is from 1550s; that of "porcupine spine" is from c.1600.

hollow, horny barrel of a bird's feather, used as the principal writing instrument from the 6th century until the mid-19th century, when steel pen points were introduced. The strongest quills were obtained from living birds in their new growth period in the spring. Only the five outer wing feathers (follicles) were considered suitable for writing; the second and third were especially preferred. Quills from the left wing were favoured because the feathers curve outward and away from a right-handed writer.
