a fragile human truce with time, scribbled over and ignored anyway
means A system or chart that organizes days, weeks, and months across a year, used to track dates and plan events.
from From Latin 'calendarium,' an account book of debts — named for the 'kalendae' (Calends), the first day of each Roman month, when interest came due and bills were settled. So the word for time began as the word for what you owed; we've been counting days and dreading deadlines ever since. It reached English via Old French 'calendier.'
