The icon is depicting a calendar that is rectangular with sharp edges and a line dividing the top portion from the bottom. In the center of the object is written plus one 'd' indicating plus one day on the calendar.
This Plus 1 Day icon is a responsive icon. This means that it's optimized for four resolutions, from tiny 16x16 until highly detailed 80x80. The style comes from the latest Microsoft Office
, which makes it perfect for any Windows applications, in particular, those with ribbon toolbar control. Unlike other icon packs that have merely hundreds of icons, this monster icon pack contains 16,000 icons, all in the same style and quality.
