Google Calendar で新しくカレンダーを作成する方法

まだ不明。
でもCreating new calendarsに以下の説明がある。

To create a new calendar, first create the Atom or JSON-C code for a calendar <entry> element or data object like the ones in the previous example. For example, you might create the following code to represent a calendar to keep track of your Little League team:

{
  "data": {
    "title": "Little League Schedule",
    "details": "This calendar contains the practice schedule and game times.",
    "timeZone": "America/Los_Angeles",
    "hidden": false,
    "color": "#2952A3",
    "location": "Oakland"
  }
}

ここらへんいじれば何とかなるのかなー？
