# Sample ICS calendar files for testing, free and CC0 2 ICS test files from 318 B to 403 B. Direct URLs, a SHA-256 for each and CC0, so curl and CI can fetch them with no signup and no keys. The page: . iCalendar files are exchanged between every calendar application, and the corners where implementations disagree are well known: time zones, all-day events and recurrence. `ics/single-event.ics` is the simple case: one timed event of an hour with a summary, description and location, in UTC. `ics/recurring-weekly-rrule.ics` is the one that finds bugs: a weekly series of ten occurrences expressed as a single event plus an `RRULE`, which the client has to expand itself. Code that only reads `DTSTART` shows one event where there should be ten. Every line is folded at 75 octets as the specification requires, and nothing in either file comes from the machine that generated it: timestamps and UIDs are derived from a seed, so the files are byte for byte identical on every build and contain no personal data. Use them to test calendar imports, invitation parsing and anything that has to expand a recurrence rule correctly.
