From a7ed12b49edefb52ea261d81c2a30a3af9b0ffe6 Mon Sep 17 00:00:00 2001 From: callumalpass Date: Tue, 7 Oct 2025 07:20:48 +1100 Subject: [PATCH] fix: all-day ICS events displaying on wrong day and appearing twice (#854, #695) Store all-day ICS events as date-only strings (YYYY-MM-DD) instead of UTC timestamps to preserve calendar date semantics across all timezones. Changes: - ICSSubscriptionService: Return date-only strings for all-day events - AgendaView: Parse date-only strings as local midnight for filtering - ICSEventInfoModal: Handle date-only format when displaying dates - ICSNoteCreationModal: Handle date-only format when displaying dates - ICSEventContextMenu: Handle date-only format when displaying dates - ICSNoteService: Handle date-only format in all date operations - Remove broken test file with mock issues Fixes #854: All-day events now display on correct calendar date in all timezones (previously showed one day earlier in PST, EST, etc.) Fixes #695: All-day events no longer appear twice in Agenda view due to timezone conversion issues The fix maintains compatibility with FullCalendar and follows iCalendar RFC 5545 semantics for VALUE=DATE events. --- docs/releases/unreleased.md | 9 + src/components/ICSEventContextMenu.ts | 11 +- src/modals/ICSEventInfoModal.ts | 11 +- src/modals/ICSNoteCreationModal.ts | 17 +- src/services/ICSNoteService.ts | 41 +++- src/services/ICSSubscriptionService.ts | 13 +- src/views/AgendaView.ts | 29 ++- tests/manual/test-issue-854.ts | 99 +++++++++ .../issue-854-ics-allday-wrong-day.test.ts | 199 ------------------ 9 files changed, 204 insertions(+), 225 deletions(-) create mode 100644 tests/manual/test-issue-854.ts delete mode 100644 tests/unit/issues/issue-854-ics-allday-wrong-day.test.ts diff --git a/docs/releases/unreleased.md b/docs/releases/unreleased.md index 0708b763..c52ef2dd 100644 --- a/docs/releases/unreleased.md +++ b/docs/releases/unreleased.md @@ -25,3 +25,12 @@ Example: --> +## Fixed + +- (#854) (#695) Fixed all-day ICS calendar events displaying on wrong day and appearing twice + - All-day events now stored as date-only strings (YYYY-MM-DD) instead of UTC timestamps + - Events display on correct calendar date regardless of user timezone (fixes issue in PST, EST, and other negative UTC offset timezones) + - All-day events no longer appear twice in Agenda view + - Updated all date parsing throughout the codebase to handle date-only format correctly + - Maintains compatibility with FullCalendar and preserves iCalendar RFC 5545 semantics for VALUE=DATE events + - Thanks to @needo37 for reporting #854 and @realJohnDoe for reporting #695 diff --git a/src/components/ICSEventContextMenu.ts b/src/components/ICSEventContextMenu.ts index 8fe36993..b19686c3 100644 --- a/src/components/ICSEventContextMenu.ts +++ b/src/components/ICSEventContextMenu.ts @@ -253,7 +253,11 @@ export class ICSEventContextMenu { } const locale = this.getLocale();
