Recurring Events
Example
from dateutil.rrule import rrule, WEEKLY, MO, WE, FR
from dateutil.parser import parse
meetings = list(rrule(
WEEKLY,
dtstart=parse("2024-01-01"),
until=parse("2024-03-31"),
byweekday=[MO, WE, FR],
))
print(f"{len(meetings)} meetings")
# Monthly on 15th
monthly = rrule(freq=rrule.MONTHLY, dtstart=parse("2024-01-15"), count=12, bymonthday=15) Pro Tip
rrule follows RFC 5545 — it handles DST transitions, end-of-month edge cases, and exclusions.
