U+23F0 · emoji since 2010
The alarm clock means wake up, time's up, or do not be late. It marks early mornings, deadlines, and reminders that the clock is ticking.
It also nags in a friendly way about appointments and that snooze button everyone loves to hit one more time.
In texting, ⏰️ does not carry a widely used hidden or slang meaning, so you can usually take it at face value. People send it just as it looks, to add a little visual touch or set the mood of a message. Only a handful of emoji have a separate texting code, and ⏰️ is not really one of them.
Its official Unicode name is the Alarm Clock emoji. In everyday chat most people just call it the alarm clock emoji or describe what it shows. Copy and paste it from the button at the top of this page.
The ⏰️ leads off a short phrase, and the rest of the words are written in cipher, every letter disguised as another emoji. Tap decipher to reveal the whole line.
