In `@ImmichFrame.Core/Helpers/CalendarExtensionMethods.cs`:
- Around line 11-13: Update the appointment metadata fallback logic in the
calendar extension method so Description and Location remain non-null strings
when occurrence.Source is not a CalendarEvent, using empty-string defaults
consistently with Appointment, IAppointment, and generated client contracts.
In `@ImmichFrame.Core/Services/IcalCalendarService.cs`:
- Line 50: Validate CalendarDaysAhead in both settings paths before the endDate
calculation in IcalCalendarService, rejecting negative values and values that
would exceed the supported DateTime range when adding the extra day. Ensure
invalid values are handled before DateTime.Today.AddDays is invoked, while
preserving normal date calculation for valid settings.
- Around line 55-57: Update the appointment aggregation in IcalCalendarService
so each calendar’s occurrences are added without per-calendar ordering, then
sort the merged appointments by StartTime immediately before returning the
aggregate; preserve the existing date range and ToAppointment conversion.

Adds a new optional setting, CalendarDaysAhead (default 0, fully backward-compatible), that widens the calendar widget's query window from "today only" to "today + N days" — useful for photo frames where a full week's view is more useful than a single day.
Also fixes a bug where recurring calendar events always displayed their original/master start date instead of the actual date of the specific occurrence returned by GetOccurrences() — this was largely invisible before since the window was always exactly one day, but breaks the whole feature once the window is widened.
Full breakdown of the 6 files changed, with diffs and testing notes, is below.

Add configurable calendar look-ahead window (
CalendarDaysAhead)Closes #627
Problem
The calendar widget only ever fetches and displays today's events
(
GetOccurrences(DateTime.Today, DateTime.Today.AddDays(1))). For apassive display like a photo frame, that means you only see what's
happening today and miss anything coming up later in the week.
While implementing this I also found and fixed a pre-existing bug: for
recurring events, every occurrence was displayed using the master
event's original start date instead of the date of the specific
occurrence found by
GetOccurrences(). This wasn't very visible beforebecause the window was always exactly "today," but it becomes obvious
(and breaks the whole feature) once the window is widened to a week.
Solution
Adds a new setting,
CalendarDaysAhead(default0, fullybackward-compatible), that widens the calendar query window from
"today only" to "today + N days." Also fixes the recurring-event date
mapping bug, and updates the frontend to show a date alongside the
time for any event that isn't today.
Files changed
1.
ImmichFrame.Core/Interfaces/IServerBehaviorSettings.csAdd the new setting to the interface.
public interface IServerBehaviorSettings { public List<string> Webcalendars { get; } + public int CalendarDaysAhead { get; } public int RefreshAlbumPeopleInterval { get; } public string? WeatherApiKey { get; } public string? WeatherLatLong { get; } public string? UnitSystem { get; } public string? Webhook { get; } public string? AuthenticationSecret { get; } }2.
ImmichFrame.WebApi/Models/ServerSettings.csAdd the concrete property (current-format
Settings.json/YAML/env path),default
0so existing configs are unaffected.public List<string> Webcalendars { get; set; } = new(); +public int CalendarDaysAhead { get; set; } = 0; public int RefreshAlbumPeopleInterval { get; set; } = 12;3.
ImmichFrame.WebApi/Helpers/Config/ServerSettingsV1.csAdd the same property to the legacy/flat V1 settings class (this is
the path used when configuring purely via environment variables with no
Settings.json/YAML present), and forward it through the V1 adapter.public class ServerSettingsV1 : IConfigSettable { ... public List<string> Webcalendars { get; set; } = new List<string>(); + public int CalendarDaysAhead { get; set; } = 0; public int RefreshAlbumPeopleInterval { get; set; } = 12; ... }class GeneralSettingsV1Adapter(ServerSettingsV1 _delegate) : IGeneralSettings { public List<string> Webcalendars => _delegate.Webcalendars; + public int CalendarDaysAhead => _delegate.CalendarDaysAhead; public int RefreshAlbumPeopleInterval => _delegate.RefreshAlbumPeopleInterval; ... }4.
ImmichFrame.Core/Services/IcalCalendarService.csUse the new setting to widen the query window, and sort results
chronologically (previously trivial since there was only ever one day's
worth of data to return).
5.
ImmichFrame.Core/Helpers/CalendarExtensionMethods.csBug fix. The
Occurrenceoverload ofToAppointment()wasdelegating to the
CalendarEventoverload whenever the occurrence'ssource was a
CalendarEvent, which usescalEvent.Start/calEvent.End— the master event's original date, not the specific occurrence's
actual date. For a weekly recurring event, every returned occurrence
therefore displayed the same (wrong) date, regardless of which
occurrence was actually found by
GetOccurrences().The fix keeps the correct per-occurrence timing
(
occurrence.Period.StartTime/EndTime) while still pullingSummary/Description/Locationfrom the source event.public static IAppointment ToAppointment(this Occurrence occurrence) { - if (occurrence.Source.GetType() == typeof(CalendarEvent)) { - return ((CalendarEvent)occurrence.Source).ToAppointment(); - } + string summary = ""; + string? description = null; + string? location = null; + + if (occurrence.Source is CalendarEvent calEvent) + { + summary = calEvent.Summary; + description = calEvent.Description; + location = calEvent.Location; + } + return new Appointment { - //Summary = occurrence.Period.Duration.Summary, - //Description = occurrence.Source.Description, + Summary = summary, + Description = description, StartTime = occurrence.Period.StartTime.AsSystemLocal, Duration = occurrence.Period.Duration, EndTime = occurrence.Period.EndTime.AsSystemLocal, - Location = "" + Location = location }; }6.
immichFrame.Web/src/lib/components/elements/appointments.svelteThe date-formatting helper only ever checked whether an event's own
start/end fell on the same day as each other (i.e. whether it spans
midnight) to decide if a date should be shown — a reasonable
simplification when every event was always "today," but it means that
once the window spans a week, non-today events still only show a time,
with no way to tell which day they're on. Now it also checks whether
the event is today, and shows the date for anything that isn't.
function formatDates(startTime: string, endTime: string) { let startDate = new Date(startTime); let endDate = new Date(endTime); - let sameDay = startDate.getDate() == endDate.getDate(); + let sameDay = startDate.toDateString() == endDate.toDateString(); + let today = new Date(); + let isToday = startDate.toDateString() == today.toDateString(); let clockFormat = $configStore.clockFormat ?? 'HH:mm'; let clockDateFormat = $configStore.clockDateFormat ?? 'eee, MMM d'; let fullFormat = clockDateFormat + ' ' + clockFormat; if (sameDay) { - return format(startDate, clockFormat) + ' - ' + format(endDate, clockFormat); + if (isToday) { + return format(startDate, clockFormat) + ' - ' + format(endDate, clockFormat); + } + return format(startDate, clockDateFormat) + ' ' + format(startDate, clockFormat) + ' - ' + format(endDate, clockFormat); } return format(startDate, fullFormat) + ' - ' + format(endDate, fullFormat); }Configuration
New optional setting, works the same way as existing settings across
all three config methods (
Settings.json,Settings.yml, environmentvariables):
CalendarDaysAhead00preserves existing today-only behavior.Example env var:
CalendarDaysAhead=7shows today plus the next 7 days.Testing performed
.icsfeed containingsingle-occurrence and weekly-recurring (
RRULE:FREQ=WEEKLY) events,including one with an
EXDATEexception.CalendarDaysAhead=0reproduces exact previous behavior(today only).
CalendarDaysAhead=7correctly returns events across thefull window, with recurring events landing on their correct
occurrence dates (previously they all incorrectly showed the
recurrence's original start date).
Settings.json-style config and pureenvironment-variable config (the legacy
ServerSettingsV1path),since these bind settings differently.
date+time for events on other days.
Known limitations / open questions for reviewers
fullFormat(date + time) on both ends; happy to adjust formatting if maintainers
have a preferred convention for all-day events specifically.
