The tear-off calendar emoji is modeled after the daily calendars that were widely used before the digital age. As a result, it gives the impression of singling out and emphasizing one important day, such as a deadline or an anniversary.

While the other calendar emoji (🗓️) shows a plan for the whole month, the 📆 emoji puts all the focus on a single day. This feature makes it effective for announcing a 'D-day' or for drawing people's attention to a specific date, like in an event notice.
