Abreißkalender

A single date on a calendar. Generally depicted as a page on a two-ringed, daily desk calendar, as flipped or torn off to change the date. Displays month and day on a white, square page, curled up at the bottom right.

Like 📅 Calendar and 🗓️ Spiral Calendar, commonly used as an icon for specific upcoming events or memorial dates. Also used for various content concerning time, date, schedules, planning, and observances and occasions more generally.

The date shown is July 17. This date was first used by Apple as a reference to when iCal for Mac premiered at MacWorld Expo in 2002. Since 2014 Emojipedia has celebrated World Emoji Day on July 17, because of this emoji.

Major platforms previously used a variety of dates on this calendar, but have changed in recent years to also show July 17, to avoid confusion on World Emoji Day. Some vendors still feature easter egg dates marking company founding or other milestones:
