アップル製でないPCでカレンダーを見ているのですが、数日前の仕様変更から
予定が日付をまたいで1日伸びた状態で表示されるようになりカレンダーが使い物になりません。
他の方（他のパソコン）は問題なく使用できているのでしょうか…？
時間指定の予定は正常に表示され、「終日」の予定だけ問題が起こります。
例えば、1月10日の終日の予定を作ると、10日と11日にまたがってその予定が表示されます。
開始日と終了日はちゃんと10日で設定されています。
15日と16日の2日間の「終日」で作ったら15・16・17日に予定が表示されます。
カレンダーがめちゃくちゃで使えないのですが、サポートの窓口にも連絡できず（よくある質問を永久に提案してくる）非常に困っています。打開策はありませんか？
Translation from Japanese:
PC version calendar "All day" schedule is displayed extended.
I'm viewing the calendar on a non-Apple PC, but due to a specification change a few days ago.
The calendar is now unusable as the schedule is displayed as extending by one day across dates.
Can other people (other computers) use it without any problems?
Timed events appear fine, only "all day" events have an issue.
For example, if you create an all-day event for January 10th, that event will be displayed across the 10th and 11th.
The start date and end date are set to exactly 10 days.
If you create an "all day" schedule for the 15th and 16th, your schedule will be displayed on the 15th, 16th, and 17th.
My calendar is messed up and I can't use it, but I can't even contact the support desk (they keep suggesting frequently asked questions), which is really annoying. Is there any solution?
I do not have an answer but translated your post in case someone else can help.
Thank you for your help.
More people will understand this question well. I really appreciate it.
One thing,
I mean the start date and end date are set for 10th, but not 10 days.
I hope someone can tell me the solution.
