【Google Calendar】Googleカレンダーの背景；日曜日を赤，土曜日を青にする

Googleカレンダーの日曜日の行を赤，土曜日の行を青で表示したいときは，
Stylishで次を追加すれば良い：
(If you want to color background of Sundays for red, Saturdays for blue in Google Calendar,
you can add the following code in Stylish:)

@namespace url(http://www.w3.org/1999/xhtml);
@-moz-document url-prefix("http://www.google.com/calendar/"), url-prefix("https://www.google.com/calendar/"){

ちなみに，これは月ビューの一番左の行を赤，右の行を青にしているだけなので，「日曜始まり」かつ「月ごと」の表示にしていないと意味なし．
(Note: because this code simply color the most left to red and most right to blue in monthly-view, please use "monthly-view" and "Sundays most left view".)
