Google カレンダーには、予定やカレンダーの詳細を作成、管理、共有できる強力なツールが用意されています。ただし、ユーザーが個々の予定の表示、作成、更新、共有を行う場合、特に他のアプリケーションから予定情報をインポートまたはエクスポートする必要がある場合は、複雑なカレンダーを効果的に管理するのに多くの時間がかかることがあります。
Google Workspace アドオンで Google カレンダーを拡張すると、ユーザーの時間を節約し、作業を効率化できます。Google Workspace アドオンを構築する際に、ユーザーが必要とする場所に直接挿入されるカスタム インターフェースを Google カレンダーに定義できます。これらのインターフェースは、カレンダー タスクの自動化、ユーザーへの追加情報の提示、新しいブラウザタブに切り替えることなくユーザーがサードパーティ システムとやり取りできるようにするのに役立ちます。
Google Workspace アドオンでは、Google カレンダー内で次の種類の拡張機能を定義できます。

However, effectively managing complex\ncalendars can take a lot of time as the user views, creates, updates, and\nshares individual events, particularly if the user must import or export\nevent information from other applications.\n\nYou can save time and effort for your users by extending Google Calendar with\nGoogle Workspace add-ons. When you build a\nGoogle Workspace add-on, you can define custom\ninterfaces that are inserted directly into Google Calendar, exactly where the\nuser needs them. These interfaces help automate calendar tasks, present\nadditional information to the user, or let the user interact with a third-party\nsystem without having to switch to a new browser tab.\n\nGoogle Workspace add-ons can define the following kinds\nof extensions within Google Calendar:\n\n- Non-contextual [homepages](/workspace/add-ons/concepts/homepages)\n- Contextual interfaces that appear when users click on an event in the calendar view.\n- Contextual interfaces that appear when users open an event to view or edit it.\n- Custom [conferencing solutions](/workspace/add-ons/calendar/conferencing/overview#conference_solutions) for Google Calendar events (see [Third-party conferencing overview](/workspace/add-ons/calendar/conferencing/overview) for details).\n\n| **Note:** You can't yet use Calendar add-ons on mobile clients.\n\nSee what you can make\n---------------------\n\nGoogle Workspace add-ons are built using\n[Apps Script](/apps-script), and their interfaces defined using the Apps Script\n[Card service](/apps-script/reference/card-service). See\n[Building Google Workspace add-ons](/workspace/add-ons/how-tos/building-workspace-addons)\nfor an overview. Google Workspace add-on behavior is\nconfigured using a\n[manifest](/workspace/add-ons/concepts/workspace-manifests), which includes\nCalendar-specific sections.\n\nWhen configuring your Google Workspace add-on to\nextend Google Calendar, you must decide what interfaces to create for your\nadd-on and what actions it can take. See the following guides for more\ninformation:\n\n- [Building Google Calendar interfaces](/workspace/add-ons/calendar/building-calendar-interfaces)\n- [Calendar actions](/workspace/add-ons/calendar/calendar-actions)\n- [Manifests](/workspace/add-ons/concepts/workspace-manifests#manifest-structure)\n\nIf you maintain a conferencing system, see\n[Third-party conferencing overview](/workspace/add-ons/calendar/conferencing/overview)\nfor details on how to integrate your conference types within Google Calendar."]]
