the.com/periodical

A magazine with the patience to show up on the same date every time.

means A publication issued at regular intervals (weekly, monthly, quarterly) rather than all at once, as opposed to a book printed complete.

from Built from 'period' plus the adjective-forming '-ical,' tracing back to Greek 'periodos' — 'peri' (around) plus 'hodos' (way, road) — literally a 'going around' or a cycle. The Greeks used it for recurring cycles of time; English borrowed that sense of regular recurrence and, by the 1700s, applied it specifically to publications that kept coming back around like clockwork.
