FAQ
Questions iCalendar RRULE Iterator owners ask.
- 01
How does the engine handle timezone changes?
The engine uses UTC-based integer math via the V8 Date object, ensuring that all calculations are deterministic and unaffected by local timezone shifts or daylight saving transitions.
- 02
Can I verify if my RRULE string is valid before processing it?
Yes, you can use the audit_rule_syntax capability to check for structural errors like missing FREQ properties or malformed intervals.
- 03
What parameters can I extract from a rule?
By using decompose_rrule, you can extract key-value pairs such as FREQ, INTERVAL, COUNT, and UNTIL to understand the rule's configuration.
