Remove ineffective UNTIL modification and unnecessary tzid clearing. Simplify timed event conversion. The removed code had no effect because rule.options is a read-only getter in rrule-temporal.
…rn timezones When looking up recurrence overrides (moved/modified instances), the dateKey was always calculated from UTC time. This caused a mismatch for full-day events in timezones east of UTC (e.g., Europe/Berlin). Example: - Full-day event on Oct 12 in Europe/Berlin (UTC+2) - Old: dateKey = "2024-10-11" (from UTC: Oct 11 22:00) - New: dateKey = "2024-10-12" (from local date components) node-ical's getDateKey() uses local date components for VALUE=DATE events, as per RFC 5545 specification. MagicMirror now matches this behavior. This fixes moved full-day recurring events not being found in their recurrence override table, causing them to appear on the wrong date.

Great 🙂 The switch from rrule to rrule-temporal at node-ical was certainly the right strategic move, but it does come with some migration pains. |

Adapts calendar module to node-ical changes and fixes a bug with moved full-day recurring events in eastern timezones.
Changes
1. Update node-ical to 0.23.1
getDateKey()behavior for VALUE=DATE events (now uses local date components)2. Remove dead code
3. Fix recurrence lookup for full-day events
node-ical changed the behavior of
getDateKey()- it now uses local date components for VALUE=DATE events instead of UTC. This broke recurrence override lookups for full-day events in eastern timezones.Why it broke:
Example:
"2024-10-12"(local date)"2024-10-11"(from UTC: Oct 11 22:00)Solution: Adapt to node-ical's new behavior by using local date components for full-day events, UTC for timed events.
Note: This is different from previous timezone fixes - those addressed event generation, this fixes the lookup of recurrence overrides.
Background
node-ical 0.23.0 switched from
rruletorrule-temporal, introducing breaking changes. Version 0.23.1 fixed the UNTIL validation issue and formalized thegetDateKey()behavior for DATE vs DATE-TIME values, following RFC 5545 specification that DATE values represent local calendar dates without timezone context.
