The calendar, upon release, immediately causes chaos, as people suddenly can keep track of time and plan ahead, thus making life aggravatingly mechanical, and also allowing people to discover how old they were. A group of hunchmen, just a few of the "very hip young people" of the world, attack Greggery on the way home from his office one night, enraged at the prospect of birthdays and being aware of their own aging. Greggery is chased by them in his car, and narrowly escapes into a cave in a conveniently placed and nearby mountain.
