This is a picture of a calendar with the number "19" showing on the front. it has two small rings at the top holding the pages together, and a bar that would most likely be for the month's name.
This is a Calendar 19 icon. We've made it in iOS style
, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 13,300 icons, all in the same style and quality.
